In Fig. 9.4, the area of parallelogram ABCD is :
a. AB × BM
b. BC × BN
c. DC × DL
d. AD × DL
We know that
Area of a parallelogram is the product of any side and its corresponding altitude
If AB is the base and DL is the height
Area of parallelogram = AB × DL
If AD is the base and BM is the height
Area of parallelogram = AD × BM
If DC is the base and DL is the height
Area of parallelogram = DC × DL
Therefore, the area of parallelogram is DC × DL.
