Expert Answer:

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
