More about the area
General information
Area is the size of a geometric figure in two-dimensional space. It is used in mathematics, medicine, engineering, and other sciences, such as calculating the cross section of cells, atoms, or pipes such as blood vessels or water pipes. In geography, area is used to compare the sizes of cities, lakes, countries, and other geographic features. Area is also used in population density calculations. Population density is defined as the number of people per unit area.
Units
Square meters
Area is measured in SI units in square meters. One square meter is the area of a square with a side of one meter.
unit square
A unit square is a square with sides of one unit. The area of a unit square is also equal to unity. In a rectangular coordinate system, this square is at coordinates (0,0), (0,1), (1,0) and (1,1). On the complex plane, the coordinates are 0, 1, i and i+1, where i is an imaginary number.
Ar
Ar or sotka, as a measure of area, is used in the CIS countries, Indonesia and some other European countries, to measure small urban objects such as parks, when a hectare is too large. One are is equal to 100 square meters. In some countries, this unit is called differently.
Hectare
Real estate is measured in hectares, especially land plots. One hectare is equal to 10,000 square meters. It has been in use since the French Revolution, and is used in the European Union and some other regions. As well as ar, in some countries the hectare is called differently.
Acre
In North America and Burma, area is measured in acres. Hectares are not used there. One acre is equal to 4046.86 square meters. Initially, an acre was defined as the area that a peasant with a team of two oxen could plow in one day.
barn
Barns are used in nuclear physics to measure the cross section of atoms. One barn equals 10⁻²⁸ square meters. Barn is not a unit in the SI system, but is accepted for use in this system. One barn is approximately equal to the cross-sectional area of the uranium nucleus, which physicists jokingly called "huge as a barn." Barn in English "barn" (pronounced barn) and from a joke of physicists, this word became the name of a unit of area. This unit originated during World War II, and scientists liked it because its name could be used as a code in correspondence and telephone conversations within the Manhattan Project.
Area calculation
The area of the simplest geometric figures is found by comparing them with the square of a known area. This is convenient because the area of a square is easy to calculate. Some formulas for calculating the area of geometric shapes below are obtained in this way. Also, to calculate the area, especially a polygon, the figure is divided into triangles, the area of \u200b\u200beach triangle is calculated using the formula, and then added. The area of more complex figures is calculated using mathematical analysis.
Area formulas
- Square: square side.
- Rectangle: product of the parties.
- Triangle (side and height are known): the product of a side and the height (the distance from that side to the edge) divided in half. Formula: A = ½ah, where A- square, a- side, and h- height.
- Triangle (two sides and the angle between them are known): the product of the sides and the sine of the angle between them, divided in half. Formula: A = ½ab sin(α), where A- square, a and b are the sides, and α is the angle between them.
- Equilateral triangle: side, squared, divided by 4 times the square root of three.
- Parallelogram: the product of a side and the height measured from that side to the opposite side.
- Trapeze: the sum of two parallel sides multiplied by the height, divided by two. Height is measured between these two sides.
- A circle: the product of the square of the radius and π.
- Ellipse: product of semiaxes and π.
Surface area calculation
You can find the surface area of simple three-dimensional figures, such as prisms, by unfolding this figure on a plane. It is impossible to obtain a ball scan in this way. The surface area of a sphere is found using the formula by multiplying the square of the radius by 4π. From this formula it follows that the area of a circle is four times less than the surface area of a ball with the same radius.
Surface areas of some astronomical objects: Sun - 6.088 x 10¹² square kilometers; Earth - 5.1 x 10⁸; thus, the surface area of the Earth is about 12 times smaller than the surface area of the Sun. The surface area of the Moon is approximately 3.793 x 10⁷ square kilometers, which is about 13 times smaller than the surface area of the Earth.
planimeter
The area can also be calculated using a special device - a planimeter. There are several types of this device, for example, polar and linear. Also, planimeters are analog and digital. In addition to other features, digital planimeters can be scaled to make it easier to measure features on a map. The planimeter measures the distance traveled along the perimeter of the measured object, as well as the direction. The distance traveled by the planimeter parallel to its axis is not measured. These devices are used in medicine, biology, engineering, and agriculture.
Area properties theorem
According to the isoperimetric theorem, of all figures with the same perimeter, the circle has the largest area. If, on the contrary, we compare figures with the same area, then the circle has the smallest perimeter. The perimeter is the sum of the lengths of the sides of a geometric figure, or a line that marks the boundaries of this figure.

Kilometers when measuring a road, simply multiply the length of the road by its width. Convert the road width to kilometers as well. Since the width of the road is usually given (measured) in meters, simply divide the width of the road (in meters) by 1000. If the width of the road is not constant, then convert to square kilometers each section that has the same width. Then add up the resulting areas. If the accuracy of the calculations is not important, take its average width as the width of the road. If the highway is a federal highway, then find its width in the appropriate reference books (for example, atlases of motorists). For approximate calculations, take the width of the central highway equal to 8 (0.008 km) - this is the average width of the route of federal highways.
Search engines also know how to convert area units. Load, for example, the main page of the Google search engine and enter the appropriate query. Let's say if you want to convert 1587 m?, then the query might look like this: "1587 square to square kilos meters". The Google calculator will recalculate and display the result: “1587 (sq. meters) = 0.001587 sq. kilometer".

To solve problems correctly, it is necessary to ensure that the units of measurement correspond to a single system. Traditionally, an international measurement system is used to solve mathematical and physical problems. If the values are given in other systems, they must be converted to international (SI).
You will need
- - tables of multiples and submultiples;
- - calculator.
Instruction
One of the main quantities that are measured in applied sciences is length. Traditionally, it was measured in steps, elbows, versts, etc. Today, the basic unit of length is 1 meter. Submultiple values from it - , etc. For example, to convert centimeters to meters, you need to divide them by 100. If the length is measured in kilometers, convert it to meters by multiplying by 1000. To convert national units of length, use the appropriate coefficients.
Time is measured in seconds. Other popular time units and hours. To convert minutes to , multiply them by 60. Converting hours to seconds is done by multiplying by 3600. For example, if the time it took is 3 hours and 17 minutes, then convert it to seconds like this: 3∙3600+17∙60= 11820 p.
Speed, as a derivative quantity, is measured in meters per second. Another popular one is per hour. To convert the speed to m/s, multiply it by 1000 and divide by 3600. For example, if the speed of a cyclist is 18 km/h, then this value in m/s will be 18∙1000/3600=5 m/s.

How many square meters in 1, 10, 100, 1000 acres: table
What is an acre of land? Weave of land is a unit of measurement of the size of the site, weaving is equal to one hundred square meters.
The following units are used to measure areas: square millimeter (mm 2), square centimeter(cm 2), square decimeter (dm 2), square meter (m 2) and square kilometer (km 2).
For example, a square meter is the area of a square with a side of 1 m, and a square millimeter is the area of a square with a side of 1 mm.
You can also say that in one weave of 100 square meters. meters and it will be correct if we say in hectares that one weave is one hundredth of a hectare.
- Weaving is a unit of measurement for the size of a plot, which is often used in summer cottages or agriculture. In science, it is customary to use an analogue of weaving - ar. Ar (weaving) - the area of a square with a side of 10 m.
- Based on the name of this measure, you can already guess that we are talking about hundreds of meters.
- Indeed, one weave is equal to 100 m 2.
- In other words, one weave will be equal to the area of a square with sides of 10 m.
- Accordingly, in ten acres there will be 1000 m 2.
- 100 acres contain 10,000 m 2, and 1000 acres contain 100,000 m 2.
- In other words, to calculate how many square meters are in a given number of acres, you need to multiply the acres by 100.

- 1 weave \u003d 0.01 ha \u003d 0.0001 sq. km
- To calculate how many acres are in square meters, you need to divide the given number of square meters by 100.
- Thus, in 1 m 2 there are 0.01 weave, in 10 m 2 - 0.1 weave, and in 100 m 2 - 1 weave.
What is a hectare of land?
Hectare- a unit of area in the metric system of measures used to measure land. Field areas are measured in hectares (ha). A hectare is the area of a square with a side of 100 m. So, 1 ha is equal to 100,100 square meters, that is, 1 ha = 10,000 m 2.
Abbreviated designation: Russian ha, international ha. The name "hectares" is formed by adding the prefix "hecto..." to the name of the area unit "ar"
1 ha \u003d 100 ar \u003d 100 m x 100 m \u003d 10,000 m 2
- A hectare is a unit for measuring the size of a plot, which is equal to the area of a square with sides of 100 m. A hectare, like a weave, is mainly used as measuring units only in agriculture and summer cottages.
- The designation of a hectare looks like "ha".
- One hectare is equal to 10,000 m 2 or 100 acres.
How many square meters in 1, 10, 100, 1000 hectares: table
- In order to calculate how many square meters in a given number of hectares, you need to multiply the number of hectares by 10,000.
- Thus, there are 10,000 m 2 in 1 ha, 100,000 m 2 in 10 ha, 1,000,000 m 2 in 100 ha, and 1,000,000 m 2 in 1000 ha.
Thus, one hectare corresponds to 10,000 m2. It can easily fit a football field (0.714 hectares) or more than 16 summer cottages (the area of each is 6 acres). Well, Red Square will be twice as large as one hectare, its area is 24,750 m 2.
1 square kilometer is 100 times larger than 1 hectare. Similarly, we determine: 1 ha - how many acres are in the composition. One weave covers an area of 100 square meters. Therefore, in comparison with a hectare, weaving is 100 times less than a hectare.
- 1 weave\u003d 10 x 10 meters \u003d 100 m 2 \u003d 0.01 ha
- 1 hectare (1 ha)\u003d 100 x 100 meters or 10,000 m 2 or 100 acres
- 1 square kilometer (1 km2)\u003d 1000 x 1000 meters or 1 million m 2 or 100 hectares or 10,000 acres
- 1 square meter (1 m 2)= 0.01 acres = 0.0001 ha
