## How to Find the Area of an Ellipse?

The area of an ellipse is defined as the amount of space enclosed within the boundary of an ellipse. It is measured in square units. The formula to calculate the area of an ellipse is given by

**Area of an ellipse = π a b square units**

Where 'a' is the length of the semi-major axis and 'b' is the length of the semi-minor axis.

**Solved Example:**

Find the area of an ellipse whose length of the semi-major axis is 5 units and the length of the semi-minor axis is 9 units

**Solution:**

Given: Semi-major axis(a) = 5 units and semi-minor axis(b) = 9 units

=** **π a b

= 3.14 × 5 × 9

= 141.37 square units

Therefore, the area of an ellipse is 141.37 square units.

Similarly, you can try the calculator to find the area of an ellipse for the following:

- Length of the semi-major axis(a) = 7 units and semi-minor axis(b) = 9 units
- Length of the semi-major axis(a) = 11 units and semi-minor axis(b) = 14 units
