Question

The perimeter of regular octagon shaped swimming pool is 42 feet. What is the length of each side of the pool? a. 5 feet c. 5 feet 2 inches b. 5 feet 3 inches d. 5.2 feet

Answer 1

A regular octagon means a polygon with eight equal sides.

Perimeter means the sum of all of the sides.

8s=42  divide both sides by 8

s=5.25 feet 

and .25ft(12in/ft)=3in so each side of this octagon is:

5 ft 3 in
