Question

The area of a rectangular field is $1600sqm$. If the length of the field is $80m$, find the perimeter of the field.

Answer 1

Area of the rectangular field $=1600m^2$
$\Rightarrow length\times breadth=1600m^2$
$\Rightarrow Breadth=\frac{1600}{80}m=20m$
Now, perimeter of the rectangular field
$\Rightarrow 2\times (length+breadth)=2\times (80+20)m=2\times 100=200m$.
