Question

8 The perimeter P of a regular pentagon is 90 cm. What is the length x of each
side?

Answer 1

X = 18

Explanation:

This is a regular pentagon, meaning that each side is the same. Now, since we know the perimeter, we can divide that by 5 to find each side's length (x). 90/5 = 18, so the length x of each side is 18.

Answer 2

18cm

Explanation:

You would do 90/5 which is 18. Each side of the pentagon is 18cm.
