x²/2 =271 represents the situation where taking length twice as breadth and area as 271 ft² .
Area of a figure is the amount of space acquired by the figure
Area of a rectangle=Length x breadth
length=x
breadth=x/2
Area of rectangular lawn=lxb
=x.x/2
But as per question,
Area=271 ft²
⇒x²/2=271 1
⇒x=23.28 ft²
Therefore, x²/2 =271 represents the situation where taking length twice as breadth and area as 271 ft² .Value of x i.e. length is 23.28 ft²
