Question

The height of a parallelogram is one-third of its base. If the area of the parallelogram is $108c{m}^2$ then find its base and height.

Answer 1

Let $l$ and $h$ be the length and height respectively (in cm)

Given $l=3h$

Area =$108c{m}^2$

Area=$l\times h=3h\times h=108$

$3h^2=108$

$h=6cm$

So $l=18cm$
