# In Fig. 9.4, the area of parallelogram ABCD is :

a. AB × BM

b. BC × BN

c. DC × DL

d. AD × DL

**Solution:**

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.
