## How to Find Area of Octagon?

Octagon is defined as a two-dimensional geometrical figure and its name is derived from Greek words "octa" which meant "eight" and "gon" which meant "angles" and it is an eight-sided polygon

The area of an octagon is defined as the amount of space enclosed within the boundary of an octagon

** Area of Octagon = 2s ^{2}(1+√2) = 4.828 s^{2} square units**

where,'s' is the length of the side of an octagon

**Solved example:**

Find area of an octagon whose length of a side is 8 units.

**Solution:**

Area of octagon = 4.828s^{2}

= 4.828 × 8^{2}

= 4.828 × 64

= 309.01 square units

Therefore, the area of an octagon is 309.01 square units.
