Problem Statement

Let [ABCD][ABCD] be a parallelogram and PP a point between CC and DD. The line parallel to ADAD that passes through PP intersects the diagonal ACAC in QQ. Knowing that the area of [PBQ][PBQ] is 22 and the area of [ABP][ABP] is 66, determine the area of [PBC][PBC]. https://cdn.artofproblemsolving.com/attachments/0/8/664a00020065b7ad6300a062613fca4650b8d0.png
