Question

The perimeter of a geometric figure is the sum of the lengths of its sides. If the perimeter of the pentagon to the right​ (five-sided figure) is 80 ​meters, find the length of each side.

Answer 1

16 m

Explanation:

If the perimeter of an equilateral pentagon is 80 m and it has five sides, the length of each side must be 16 m:

`x=(80)/(5)`

`x=16`

Therefore, if each side is 16 m in length, 2½ sides must equal 40 m:

`2.5x=2.5(16)`

`2.5x=40`
