The apothem of a regular heptagon is 5.19 ft. The area is 90.825 square feet. Find the side lengths of the heptagon

Side length of the heptagon is 2.5 ft.

Step-by-step explanation:

To find the area of the heptagon, we can use the formula,

A = nsr

n = number of sides

s = side length

r = apothem

Now we can rearrange the formula to get the side as,

s = A/nr

 = 90.825 /  7 ×5.19

= 2.5 ft

So the side length of the heptagon is 2.5 ft.
