The image above is an ellipse.

To compute the area of an ellipse, two essential parameters are needed and this parameters are** axis (a)** and** axis (b).**

A = πab

Where;

A = Area of the ellipse

a = Axis of the ellipse

b = Axis of the ellipse

Let’s solve an example;

Find the area of an ellipse when it has an axis (a) of 10 cm and an axis (b) of 17 cm.

This implies that;

a = Axis of the ellipse = 10 cm

b = Axis of the ellipse = 17 cm

A = πab

A = 3.142 x 10 x 17

A = 534.14

Therefore, the **area of the ellipse** is **534.14 cm ^{2}.**

**Calculating the Axis (a) of an ellipse using Area of the ellipse and Axis (b) of the ellipse.**

a = ^{A} / _{πb}

Where;

a = Axis of the ellipse

A = Area of the ellipse

b = Axis of the ellipse

Let’s solve an example;

Find the axis (a) of an ellipse when the area of the ellipse is 210 cm^{2} with an axis (b) of 19 cm.

This implies that;

A = Area of the ellipse = 210 cm^{2}

b = Axis of the ellipse = 19 cm

a = ^{A} / _{πb}

a = ^{210} / _{3.142 x 19}

a = ^{210} / _{59.70}

a = 3.52

Therefore, the **axis (a) of an ellipse** is **3.52 cm.**

**Calculating the Axis (b) of an ellipse using the Area of the ellipse and Axis (a) of the ellipse.**

b = ^{A} / _{πa}

Where;

b = Axis of the ellipse

A = Area of the ellipse

a = Axis of the ellipse

Let’s solve an example;

Find the axis (b) of an ellipse with an area of 320 cm^{2} and an axis (a) of 120 cm.

This implies that;

A = Area of the ellipse = 320 cm^{2}

a = Axis of the ellipse = 120 cm

b = ^{A} / _{πa}

b = ^{320} / _{3.142 x 120}

b = ^{320} / _{377.04}

b = 0.85

Therefore, the **axis (b) of the ellipse** is **0.85 cm.**
