## 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.

Similarly, you can try the calculator to find the area of an octagon with the following length of sides given.

1) side = 7units 2) side = 12units
