<span>Let x= measure of sides that have common length
then from "the third side measures 5m less than twice the common length."
2x-5= third side
.
Because they gave us the perimeter we have:
11 = x+x+2x-5</span><span>11 = 4x-5
16 = 4x
4 m = x
.
third side:
2x- 5 =2(4)-5 = 8-5= 3m</span>
Length answers:
4m, 4m, and 3m
Do first a times b then multiply that by 2
