  1. Since it is a right triangle and 52 mm is the longest side, it is the hypotenuse and the other short side length is
    sqrt[(52)^2 - (20)^2] = 48 mm

    For a right triangle, either short side can be considered the base and the other short side can be considered the height. That lets you calculate the area easily.

    The area is (1/2)*(20)*(48) = 480 mm^2
    Add the three sides for the perimeter
