Statement 1: Insufficient.

Statement 2: Insufficient.

(1)+(2)= Area of triangle PST+Area of the triangle QRU= Area of rectangle- Area of parallelogram=40-32=8. Since PT is parallel to RU. Since, PST and QRU are congruent trainagle, which menas, bothe areas are equal.
Hence, 2*Area PST=8/2=4. Sufficient.

IMO, Option C.
