Question

The Jones family is building a patio in the shape of a regular heptagon. They used exactly 120.4 feet of trim around its edges. What is the length of one side of the patio?

Answer 1

EXPLANATION

Let's see the facts:

Amount of trim= 120.4 feet

The perimeter of a regular heptagon is Perimeter=7s

So, substituting the terms:

120.4 = 7s

Switching sides:

7s = 120.4

Dividing both sides by 7:

s=120.4/7

Simplifying:

s = 17.2

The length of one side is 17.2 feets
