Question

From the top **A** of a vertical wall **AB** of height **$$30 \, 	ext{m}$$**, 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 **$$	ext{m}^2$$**) of the quadrilateral **BCPQ** is equal to:
