In trapezoid ABCD segments AB and CD are parallel. Point P is the intersection of diagonals AC and BD. The area of APAB is 16 square units, and the area of ▲PCD is 25 square units. What is the area of trapezoid ABCD?

Since triangles APAB and PCD are both right triangles, and they share the hypotenuse AP, they are similar triangles. Let x be the length of AP. Then the length of PB is x, the length of PC is 5x, and the length of PD is 4x.

The area of trapezoid ABCD is:

(1/2)(x + 4x)(5x) = 15x^2 = 15(16) = 240 square units
