To find the perimeter<span> of a polygon, take the sum of the length of each side. The formula for </span>perimeter<span> of a triangle would be the sum of the three side lengths (a +b+c). In the case, where it is a regular polygon, the perimeter would be 3 times the side length. Hope this answers the question.</span>
<span>8 - 3x - 5x = -8
8 - 8x = -8
-8x = -8 - 8
-8x = -16
8x = 16
x = 16/8
x = 2</span>
