Answer 1

Step-by-step explanation:

Area of a parallelogram ABCD= area of congruent triangles ABD and BDC.

We know congruent triangles have equal area.

Given area of triangle DPB=30 sq cm

Hence, area of triangle PBC=20 sq cm .... [DP:PC=3:2]

Hence, area of triangle BDC=50 sq cm.

Area of triangle ABD= area of triangle BDC=50 sq cm.

Therefore, area of parallelogram ABCD=50+50=100 sq.cm.
