Given: Area of parallelogram=1470 cm
2
Base(AB)=35 cm and base(AD)=49 cm
Since, Area of parallelogram=base×height
⇒1470=35×DL
⇒ DL=
35
1470
⇒ DL=42 cm
Again, Area of parallelogram=base×height
⇒1470=49×BM
⇒BM=
49
1470
⇒BM=30 cm
Thus, the lengths of DL and BM are 42 cm and 30 cm respectively.
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=351470
⇒ DL=42 cm
Again, Area of parallelogram=base×height
⇒1470=49×BM
⇒BM=491470
⇒BM=30 cm
Thus, the lengths of DL and BM are 42 cm and 30 cm respectively.
