Find the perimeter and area of a right triangle if the shortest side is 20 mm. and the longest side is 52 mm.

    The longest side of a right triangle is the hypotenuse, c in
    a^2 + b^2 = c^2
    so
    a^2 + 20^2 = 52^2
    a^2 = 2704 - 400 = 2304
    a = 48

    perimeter = 48 + 20 + 52 = 120 mm
    area = (1/2)48(20) = 480 mm^2
