Given:

Area of parallelogram $=1470\ cm^2$

$AB=35\ cm$ and $AD=49\ cm$

To do:

We have to find the length of $BM$.

Solution:

We know that,

Area of parallelogram of base b and height h $=b\times h$

This implies,

$1470=49\times BM$

$BM= \frac{1470}{49}\ cm$

$BM=30\ cm$

Therefore, the length of BM is 30 cm.
