Find the area of a regular octagon with an apothem 9.7 meters long and a side length of 8 meters. a. 155.2 m2 c. 620.8 m2 b. 310.4 m2 d. 271.6 m2

The area of a regular octagon is:

A = a * P / 2,  where a is an apothem and P is a perimeter.

P = 8 * 8 m = 64 m

A = 9.7 m * 64 m / 2

A = 620.8 / 2 m²

A = 310.4 m²

The area of a regular octagon is 310.4 m².

Hope this helps!
