The bases of trapezoid ABCD are AB and CD. Let P be the intersection of diagonals AC and BD. If the areas of triangles ABP and CDP are 8 and 18, respectively, then find the area of trapezoid ABCD.
I'm so confused... please help! I was thinking that if I found the bases and heights of the two triangles I can solve the problem, but I have no idea how to go about doing it?
