A rectangular playing field is twice as long as it is broad. If its area is 0.5294km2, find in Km, the perimeter of the field.

let Length be be $b$ ,

given : $l=2b$

and area, $lb=0.5294$

put $l=2b$ in equation of area,

$2b^2=0.5294 \implies b^2=0.2647 \implies b=0.5144$

and $l=1.0288$

perimeter =$2(l+b)=3.0864$ km
