The short side of an isosceles triangle is 16cm long. Increasing each side length by 24cm doubles the perimeter. how long are the other sides of the original triangle? explain your reasoning.

p = 2x + 16
2p = (2x + 16) + 3(24)
p = 72
2x + 16 = 72
2x = 56
x = 28

all three sides
side 1-16
side 2-16
side 3-40
atriangle has three sides so if u add 24 to each one of them, it is equal to 72
so the real traingles perimeter plus 72 equals double the real perimiter. So the perimeter equals 72, if the shortest side is 16 and we can asume that there are 2 sides with measuremnets of 16, we can substitue
16+16+x=72.
So, x=40 which is side 3
