Solution

In figure if parallelogram ABCD and rectangle ABEF are of equal area, then perimeter of ABCD > Perimeter of ABEM.

Explanation:

If parallelogram ABCD and rectangle ABEF are of equal area then perimeter of ABCD > Perimeter of ABEM because:

As we know that, the perpendicular distance between two parallel sides of a parallelogram is always less than the length of the other parallel sides.

BE < BC and AM < AD.

Concept: Corollary: A rectangle and a parallelogram on the same base and between the same parallels are equal in area.
