Each side of the square is 15m. Find the length of each side of the triangle. P = 4(15) = 60 = 20 m, side of the triangle Answer by bucky(2189)   (Show Source): You can put this solution on YOUR website!Since each side of the square is 15 meters, the perimeter of the square is 4 sides times 15 meters per side = 60 meters. . So the equilateral triangle (3 congruent sides) must have a perimeter of 60 meters. Just divide the 60 meter perimeter by 3 sides and you get 20 meters per side. The answer to this problem is that the length of each side of the triangle is 20 meters. . Hope this helps you to understand how to do this problem.
