We know that

Area of parallelogram  = base \times height

Here, 

Base of parallelogram(AB) = 35 cm

and

Height of parallelogram(DL) = h cm

\Rightarrow 1470 = 35 \times h

\Rightarrow h = \frac{1470}{35} = 42 \ cm

Similarly,

Area is also given by AD \times BM

\Rightarrow 1470 = 49 \times BM

\Rightarrow BM = \frac{1470}{49} = 30 \ cm

Therefore, the value of BM and DL are  is  30cm and 42cm respectively
