Respuesta :
let Length be [tex] l [/tex] 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
The perimeter of the field will be equal to 3.0864 km.
What is a perimeter?
A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. The perimeter of the rectangle is the sum of all the sides of the rectangle.
It is given that a rectangular playing field is twice as long as it is broad. If its area is 0.5294 square km.
The perimeter of the field will be calculated as below:-
let Length be b
l=2b
l x b=0.5294
Put l=2b in the equation of area,
2b²=0.5294
b² =0.2647
b=0.5144 and l=1.0288
The perimeter will be calculated as:-
perimeter =2(l+b)=3.0864 km
Therefore, the perimeter of the field will be equal to 3.0864 km.
