Question

A regular pentagon is shown

Answer 1

Answer: The equation is 5x = 125

Step-by-step explanation:

A pentagon is a five sided figure so all the side lengths must be equal. And to find the perimeter of a pentagon the you will  the five equal side lengths.

So assume we don't know the side lengths so we will represent it by x and the side lengths are 5 so we will have five x's and they will add up to 125 and that could be represent by the equation.

x + x + x + x + x = 125

5x = 125

x = 25
