Question

If the sides of a polygon are x + 3 units, 2x – 4 units, 5x units, and 7x + 8 units, then find the perimeter of the polygon.

Answer 1

The answer is 15x + 7

Explanation:

Since the perimeter of a REGULAR polygon is the number of sides multiplied by the length, and the lengths of the sides are all different, it can be assumed that this is an irregular polygon. That means the formula to find the perimeter changes to all the sides added together.

1 x + 3

2 x - 4

5 x + 0

+ 7 x + 8

15 x + 7
