Question

If breadth and perimeter of a rectangle are $12.5cm$ and $101cm$ respectively. Find out the length of the rectangle.

Answer 1

Breadth of the rectangle $=12.5cm$

Perimeter of the rectangle $=2(l+b)$

According to the question,

$\Rightarrow 2(l+b)=101cm$

$\Rightarrow l+b=\frac{101}{2}$

$\Rightarrow l+b=50.5cm$

$\Rightarrow l=50.5-12.5$

$\Rightarrow l=38cm$

Therefore, length of the rectangle is $38cm$.
