Answer 2

Answer:

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.
