As shown in the diagram, a rectangular piece of paper ABCD was folded along CP where P is located one-third of the way from A to B. We know the total area covered by the folded paper is 213 square inches with a 75 square inch overlapping area. Find the area of triangle B' C Q in square inches.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[APCB'QD] = 213 in2
[CQP] = 75 in2
[PRQ] = [B'CQ]
[ADRP] = [B'CP]
[B'CQ] = 1/3(213 - 150) = 21 in2
