Question from eddie, a parent:

I need to make one wood box in octagon type, that has 1125.00 square feet.
I want to know how many feet in one side

Hi Eddie,

Sue answered a similar question for Christopher who wanted a 10,000 square foot octagon. She answered him by developing a relationship between the area A of a regular octagon and the side length x. The relationship is

a as a function of A

Substitute A = 1125 square feet and solve for x.
