Question

The length of a rectangular field is twice its breadth. If the perimeter of the field is $288m$. Find the dimensions of the field.

Answer 1

Let the breadth of rectangular field be $x$.

Then its length will be $2x$.

Given, perimeter $=288m$

$⟹2(l+b)=288m$

$2(x+2x)=288$

$6x=288$

$x=48m$

Now, length will be $2x=2\times 48=96m$ .

Therefore, length and breadth of a rectangular field are $96m$ and $48m$ respectively.
