Question

A polygon is regular if each of its sides has the same length. Find the perimeter of the regular polygon.

Answer 1

3 units

Explanation:

5-2x = -4x +9

-2x+4x=9-5

2x=4

x=2

substitute x = 2

5-2x

5-2(2)

5-4=1

To find the perimeter, just add all the sides

since one side is 1 unit, multiply by 3 because there are 3 sides
