Question 6
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.
Given: Area of parallelogram = 1470 cm2
Base (AB) = 35 cm and base (AD) = 49 cm
Since, area of parallelogram = base×height
On substituting the values we get,
⇒ 1470=35×DL
⇒ DL=147035
⇒ DL = 42 cm
Again, Area of parallelogram = base×height
⇒ 1470=49×BM
⇒ BM=147049
⇒ BM = 30 cm
Thus, the lengths of DL and BM are 42 cm and 30 cm respectively.
