QUESTION :

What will be the area of a rectangle if its length is halved and breadth is 4 times?

GIVEN :

$New\:Length = \dfrac{1}{2} \;of\;original\; length$

$New Breadth = 4\times Original\;Breadth$

To Find:

Area of a rectangle = ?

SOLUTION:

Let original length be $l$

⇒New length =  $\dfrac {l}{2}$

Let original breadth be $b$

⇒New length = 4b

$\boxed{Area\ of\:Triangle = l\times b}$

⇒Area =  $\dfrac {l}{2}$  × 4b

          = $2lb$
