Question

Length of a rectangle exceeds its breadth by $5m$. If the perimeter of the rectangle is $90m$. Find its length and breadth.

Answer 1

Let breadth of rectangle be $x$.

Then, its length = $x+5$

Now, Perimeter = 90 m

$2(x+x+5)=90$

$2x+5=45$

$2x=40$

$x=20m$

Therefore, length = $25m$ and breadth = $20m$.
