All you really need is the side length.
A=2(1+sqrt(2))x^2
Fill 8.93 in for x and you get an area of 385.04.

The area of a regular polygon can be found using the formula:

A = (1/2) * a * p  where a is the apothem and p is the perimeter of the polygon.

An octagon has 8 sides. Because the polygon is regular, the polygon is equilateral and all 8 sides have the same length.

directrix · Answer

a = 8 

p = 8 * 8.93

A =(1/2) * a * p

A = (1/2) * 8 * ( 8 * 8.93)

A =  285.76      @darkbeautystar
