Question

Find the area of a triangle whose base is 52cm and hypotenuse is 65 cm

Answer 1

hypotenuse (hy) = 65
base (ba) = 52
height (h)^2 = 65^2 - 52^2
                  h^2=1521   
                       h=  39cm
area = 1/2 * b *h
        =   1/2 * 39 * 52
            = 2028/2
            = 1014 cm^2
