Question

Is it possible to design a rectangular mango grove whose length is twice its breadth,and the area is 800 m^2? If so, find its length and breadth ​

Answer 1

Answer:

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

Answer 2

Answer:

Rectangular Mango Grove whose length is twice it's breath.

• Let breath = x
• Let length =2x

Step-by-step explanation:

Area of Rectangle = 800m^2

l × b = 800

X × 2x = 800

2x² = 800

x² = 800÷2

x² = 400

x² = (20)²

x = 20

• Breadth of the rectangular mango Grove = 20m

• Length of rectangular mango Grove.

= 2x

= 2×20

= 40m
