Answer:
given: ABCD is a parallelogram. P is a point on produced AB.
DN ⊥ AB. AB = 8 cm and DN = 5cm
area(ΔCPD) = area(ΔCDA) [triangles formed between same pair of parallel lines and with the same base have equal areas]
= 1/2*(area ABCD) [since diagonal of a parallelogram divide it in two equal areas]
= 1/2*AB*DN
= 1/2*8*5
= 20 sq cm
