Question

The base of parallelogram is twice its height. If the area is $512c{m}^2$, find the base and the height.

Answer 1

Given :Base of parallelogram$b=2\times$height

Area of parallelogram$=b\times h=512{cm}^2$

$\Rightarrow 2h\times h=512{cm}^2$

$\Rightarrow h^2=256$

$\Rightarrow h=16$cm

Base$=2h=2\times 16=32$cm
