Answer

Side-length of square = 22.5 units Side-length of equilateral triangle = 30 units

Work Step by Step

Let side-length of square = x Let side-length of triangle = y y = 2x – 15 Perimeter of square = 4x Perimeter of triangle = 3y = 3(2x – 15) 3(2x – 15) = 4x 6x – 45 = 4x 2x = 45 x = 22.5 units y = 2(22.5) – 15 = 30 units
