Q. 2

In Q. No. 1, if AD=6 cm, CF=10 cm and AE=8 cm, find AB.

Answer :

Area of parallelogram ABCD = AD * CF (i)

Again,


Area of parallelogram ABCD = DC * AE (ii)


From (i) and (ii), we get


AD * CF = DC * AF


6 * 10 = CD * 8


CD =


= 7.5 cm


Therefore,


AB = DC = 7.5 cm (Opposite sides of parallelogram are equal)
