Area is the quantity, which determines the size of the surface, one of the basic properties of geometric figures.

The figure, which has an area called Quadrature. Area of complex geometric shapes is determined by counting the number of unit squares that figure can be covered. The figures with the same area referred to by equal.

A general method for calculating the area of geometric figures provided integral calculus.

Measured in square units in length.

For typical figures can be calculated using the following tools:
