The perimeter of MNO is equal to the perimeter of square ABCD. If the lengths of the sides of the triangle are represented by 4x + 4, 5x - 3, and 17, and one side of the square is represented by 3x, find the length of a side of the square.

Answer 1

since the perimeter of a square is 4 times a side, we clearly have

4x+4 + 5x-3 + 17 = 4(3x)

Now solve for x, and the side is 3x.
