JEE 2023 — Mathematics PYQ

From the top A of a vertical wall AB of height 30 m, the angles of depression of the top P and bottom Q of a vertical tower PQ are $15^{\circ }$ and $60^{\circ }$ respectively, B and Q are on the same horizontal level. If C is a point on AB such that $CB=PQ$, then the area (in $m^2$) of the quadrilateral BCPQ is equal to :
