1.	EXERCISE 9.21. h Fig 9.15, ABCD is a parallelogram,AE L DCAand CF i AD. If ABCF-10cm, find AD.If E,FG and H are respectively the mid-points ofthe sides of a parallelogram ABCD, show that16 cm, AE8 cm and2.D
Answer» 1)area of parallelogram is base into height and AB is equal to DC o area of the parallelogram is AE X DC = 16X8 and area of para. is also base x height = AD x FC = 10 X AD. now by comparing both the results we get AD is equal to 16 X 8 / 10 that is 12.8
