The perimeter of a rectangle is given by the formula 2(length + width). Since the rectangle is as long as it is wide, both the length and width are the same, let's call them x. So, the perimeter is 2(x + x) = 4x. Given that the perimeter is 88 cm, we solve for x: 4x = 88, which gives x = 22. Therefore, both the length and width are 22 cm.
