Question

The length and breadth of a rectangular field are in the ratio $4:5$. If the length is $20m$, find the breadth of the field.

Answer 1

Given Length $\left(l\right):$ Breadth $\left(b\right)=4:5$

Let the length be $4x$

and, the breadth $=5x$

It is given that the length is $20m$

$\therefore 4x=20$

$\Rightarrow x=\frac{20}{4}=5$

so, breadth $=5x=5\times 5=25m$

Hence, Breadth of the field is $25m$
