Since the formula of a rectangle is length*width and we know the length of one side is 5m then we can do the opposite of multiplying and divide 115 by 5 to get the length of the other side (23m).

The formula for a rectangles perimeter is all the side lengths added together. Therefore 5 + 5 + 23 + 23 = 56m
