Question

The adjacent sides of a parallelogram have length $20cm$ and $12cm$. The distance between the two shorter sides is $5cm$. Find the area of parallelogram and the distance between the longer sides.

Answer 1

Area$=b\times h$

$=5\times 12=60㎠$

$=20\times x$

$\Rightarrow x=3㎝$

$\therefore$Area$=60{cm}^2$; Distance between longer sides$=3cm$
