Question

The perimeter of this polygon is 42.5 units. What is the length of side s

Answer 1

12.5 + 12.5 + 3.75 + 2.5 + S = 42.5
25 + 3.75+ 2.5 + S= 42.5
28.75 + 2.5 + S= 42.5
31.25 + S = 42.5
42.5 - 31.25 = S
S = 11.25

Answer 2

11.25 I think because you would add up all the sides to get 31.25 then you would take 42.5 minus 31.35 to get 11.25
