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)
