ABCD and BCFE are parallelograms. If area of triangle EBC = 480 sq. cm. Calculate (i) area of parallelogram ABCD                   (ii) area of parallelogram BCFE.

EBC and parallelogram ABCD are on the same base BC and between the same parallels AD and BC.         
 ar (ABCD) = 2 ar (EBC)
Hence, ar (ABCD) = 2  480= 960 sq. cm
Parallelogram ABCD and BCEF are on the same base BC and between the same parallels AF and BC.
ar (ABCD) = ar (BCEF) = 960 sq. cm
