    Altitude Length

    A rectangle and a triangle have equal areas. The length of the rectangle is 12 inches, and its width is 8 inches. If the base of the triangle is 32 inches, what is the length, in inches, of the altitude drawn to the base?

    Area of a rectangle: l*w

    Area of a triangle: (a*b)/2

    l*w = (a*b)/2

    96 = (a*32)/2

    192 = 32a

    a = 6 inches
