What do you know about an isosceles triangle? That's right, two legs are the same length.
Given: Perimeter = 56
Perimeter = side1 + side2 + side3
Let side1 and sides 2 be the two sides of equal length. Let that value be L
Then the base (the third side) is L/3 (given in the problem)
So the perimeter

Check your answer. what is one third of 24? 8.
24 + 24 + 8 = 56 Check!
