**Reiny**, Sunday, January 6, 2013 at 3:12pmperimeter of square = 4(3x) = 12x

perimeter of triangle = 4x+4 + 5x-3 + 17 = 9x + 18

so

12x = 9x+18

3x=18

x=6

so the side of the square is 3(6) = 18

check:

perimeter of square = 4(18) = 72

sides of triangle are 28, 27 and 17

perimeter of triangle = 28+27+17 = 72
