Question

If the perimeter of the rectangular field is $200m$ and its breadth is $40m,$ then its area is $\_\_\_\_$

Answer 1

Finding the area:

Given that, the perimeter of the rectangular field is $200m$ and its breadth is $40m$

$\Rightarrow$ $2(length+40)=200$

$\Rightarrow$ $2length+80=200$

$\Rightarrow$ $2length=120$

$\Rightarrow$ $length$$=60$

Then, Area $=length\times breadth$

$=60\times 40$

$=2400c{m}^2$

Therefore, the area is $2400c{m}^2$.
