Question:
HOW TO FIND THE AREA OF AN OCTAGON
Answer:

A polygon is a two-dimensional (2-D) closed figure made up of straight line segments. 

In geometry, octagon is a polygon with 8 sides. If the lengths of all the sides and the measurement of all the angles are equal,

the octagon is called a regular octagon. In other words, sides of a regular octagon are congruent.

Each of the interior angle and the exterior angle measure 135° and 45° respectively, in a regular octagon.

Consider a regular octagon with each side a units, then

Perimeter of an Octagon = 8a

Area of an Octagon = 2a2 (1 + √2)
