Given: Area of parallelogram = 1470 cm2
Base (AB) = 35 cm and base (AD) = 49 cm
Since Area of parallelogram = base x height
⇒1470 = 35 x DL
⇒DL = 1470/35
⇒ DL = 42 cm
Again,
Area of parallelogram = base x height
⇒1470 = 49 x BM
⇒ BM = 1470/49
⇒ BM = 30 cm
Thus, the lengths of DL and BM are 42 cm and 30 cm respectively.
