Share with your friends Share 0 Neha Sethi answered this Dear student Given E and F are the mid points of the sides DC and ABSo DE=EC and AF=FBAlso ABCD is a parallelogram so opposite pair of sides are equal and parallel⇒DC=ABAlso DE=AF and EC=FBSo, DEAF and ECFB are equal in area⇒2ar △AEF=2ar△CFE [Each diagonal of a parallelogram separates it into two congruent triangles.⇒ar △AEF=ar△CFE Regards 9 View Full Answer
