You don't need a diagram. Since the triangle PQR is a right-angle triangle, you can use Pythagoras' Theorem to find the side length QR. Then you have enough information to find the area of the trapezium.
PQRS is a trapezium where PQ is parallel to SR.Given that angle PQR= angle SPR= 90 degree.
PQ=8.5 cm and PR=12.3 cm,
c)The area of the trapezium PQRS
Diagram is given in the attachment
Cant upload the diagram because the size is too big and it crosses the limit.
