    A parallelogram has a perimeter of 48 millimeters. Two of the sides are each 20 millimeters long. What is the length of each of the other two sides?

    2 sides * 20 mm each is 40 mm

    subtract this from the perimeter of 48:
    48 - 40 = 8

    Since the remaining two sides equal each other, their length is:
    8/2 = 4mm
