Question

Length of a rectangle is $16cm$ less than twice its breadth. If the perimeter of the rectangle is $100cm$, find its length and breadth.

Answer 1

Let breadth of the rectangle is $x$.

Then its length will be $2x-16$.

According to the problem,

$2(length+breadth)=100$

$2(x+2x-16)=100$

or, $6x=132$

or, $x=22$.

Then length is

$=2x-16$

$=44-16=28$ cm.
