# Area of parallelogram ABCD (Fig. 9.16) is not equal to

a. DE × DC

b. BE × AD

c. BF × DC

d. BE × BC

**Solution:**

A __parallelogram__ is defined as a quadrilateral in which both pairs of opposite sides are parallel and equal.

We know that

__Area of parallelogram__ = base × height

From the figure

Area of parallelogram ABCD = AD × BE

As AD = BC

Area of parallelogram ABCD = BC × BE

Or

Area of parallelogram ABCD = DC × BF

Therefore, the area of parallelogram is not equal to DE × DC.
