DL and BM are the heights on sides AB and AD respectively of parallelogram ABCD. If the area of the parallelogram is 1470 cm2, AB = 35 cm and AD = 49 cm, find the length of BM and DL.
It is given in the question that,
AB = 35 cm
AD = 49 cm
Area of parallelogram = 1470 cm2
We know that,
Area of parallelogram = Base × Height
1470 = AB × DL
1470 = 35 × DL
∴ DL = 
= 42 cm
We have:
1470 = AD × BM
1470 = 49 × BM
∴ BM = 
= 30 cm
Hence,
The value of BM and DL is 30 cm and 42 cm respectively
