With this application, you can calculate the area of ​​two-dimensional geometric shapes.

Calculator allows you to calculate:
1) the area of ​​the circle,
a) if the radius of the circle is known - r
b) if the diameter of the circle is known - d

2) the area of ​​the sector of the circle,
a) if the sector angle is known
b) if the arc length is known

3) the area of ​​the triangle,
a) on three sides
b) on one side and the height lowered on that side
c) on two sides and the angle between them

4) the area of ​​the parallelogram,
a) by base and height
b) on two sides and the angle between them
c) along two diagonals and the angle between them

5) the area of ​​the polygon,
a) with n sides and side length a
b) with the number of sides n, inscribed in a circle of radius r
c) with the number of sides n described around a circle of radius r

6) the area of ​​the ellipse,

7) the area of ​​the rectangle,

8) the area of ​​the trapezoid.

The area calculator allows you to calculate square kilometers (km²), square meters (m²), square centimeters (cm²), square millimeters (mm²), square feet (ft²), square yards (yard²), and square miles (miles²).
