9. In the figure, ABCD and EFGD are two parallelograms and G is the mid-point of CD.
               Then, ar (ΔDPC) = ½ ar (EFGD).












               10. n the figure, PSDA is a parallelogram. Points Q and R are taken on PS such
               that PQ = QR= RS and PA || QB || RC. Prove that ar (PQE) =ar (CFD).











               11. s any point on the diagonal PR of a parallelogram PQRS (figure). Prove that
               ar(ΔPSO) = ar(ΔPQO).











               12. ABCD is a parallelogram in which BC is produced to E such that CE = BC. AE
               intersects CD at F



















               If ar (ΔDFB) = 3 cm , then find the area of the parallelogram ABCD.
