Question -

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



Answer -

Area of rectangular mango grove = 800 m┬▓
Let breadth = x m
Then length = 2x m
According to the condition,
2x x x = 800
=> 2x┬▓ = 800
=> x┬▓ = 400 = (┬▒20)┬▓
Yes, it is possible,
x = 20, -20
But x = -20 is not possible being negative
Breadth = 20 m
and length = 20 x 2 = 40 m
