# Area of Ellipse

To calculate the **area of an ellipse**, we need to know a length of its semi-major and semi-minor axis. The **area of the ellipse** means a size of a cover area by the ellipse. For example, to know the area of an elliptic running track or any playground, you can use this formula. This formula is an approximation of integral solving. The elementary unit of the area is one square metre, it means the second power of one metre (1 m^{2}).

## Area of Ellipse - formula

**Area of Ellipse** = π × semi-major length of a × semi-minor length of b

A = π × a × b
