@AccessDenied Do you mind looking at this quickly?

It looks to me like you should find the similarity ratio / area ratio between the two triangles and find the area of the smaller triangle.  Then, subtract the smaller triangle's area from the larger triangle's area, which will just leave the trapezoid's area.
