Question

The perimeter of a rectangular swimming pool is $154m$. Its length is $2m$ more than twice its breath. What is the breadth of the pool?

Answer 1

Let the length and breadth of the pool be l and b respectively

$l-2b=2$

$=>l=2b+2$

Perimeter$=2(l+b)=154$

$=>l+b=\frac{154}{2}=77$

$=>2b+2+b=77$

$=>3b=75$

$=>b=\frac{75}{3}=25$
