Correct option is

B

Yes. 40m,20m.

⇒ Let breadth be x. Then, length will be 2x

⇒ Area of rectangular mango grove =800m

2

⇒ x×2x=800

⇒ 2x

2

=800

⇒ x

2

=400

∴ x=±20

⇒ x can not be negative

∴ x=20

⇒ Breadth of the rectangular mango grove =x=20m

⇒ Length of the rectangular mango grove =2x=20×2=40m
