Area of parallelogram ABCD (Fig. 9.16) is not equal to
a. DE × DC
b. BE × AD
c. BF × DC
d. BE × BC
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
Area of parallelogram ABCD = DC × BF
Therefore, the area of parallelogram is not equal to DE × DC.
