Question

15) DL and BM are the heights on sides AB and AD respectively of parallelogram ABCD
If the area of the parallelogram is 300 cm2 ; AB = 30 cm
AD = 15cm, Find the length of the two altitudes BM and DL.​

Answer 1

Answer:

Given: Area of parallelogram=1470 cm²

Base(AB)=35 cm and base(AD)=49 cm

Since, Area of parallelogram=base×height

⇒1470=35×DL

⇒ DL= 1470÷35

⇒ DL=42 cm

Again, Area of parallelogram=base×height

⇒1470=49×BM

⇒BM= 1470÷49

⇒BM=30 cm

Thus, the lengths of DL and BM are 42 cm and 30 cm respectively.
