Question

$DL$ and $BM$ are the height on sides $AB$ and $AD$ respectively of parallelogram $ABCD$ figure. If the area of the parallelogram is $1470c{m}^2$,$AB=35cm$ and $AD=49cm$, find the length of $BM$ and $DL$.

Answer 1

Area of the parallelogram $ABCD=AB\times DL=AD\times BM$

$⟹1470=35\times DL=49\times BM$

$⟹DL=\frac{1470}{35}$ and $BM=\frac{1470}{49}$

$\therefore DL=42$cm and $BM=30$cm
