Parallelogram ABCD and parallelogram ABEF are on the same base AB and between the same parallels AB and FC.
ar (ABCD) = ar (ABEF)
Now   ar (ADF) = begin mathsize 12px style 1 half end stylear (ABEF)
(Same base AB and between the same parallels AB and FE)
Similarly, ar (BCE) =size 12px 1 over size 12px 2ar (ABCD)
 ar (ADF) = ar (BCE)
