Yes, it is possible.
Let breadth be x m.
Then, the length = 2x m
Area of rectangle=l*b
800=x*2x
800=2x²
400=x²
20m=x
Therefore, breadth=20m
Length=(2*20)m=40m
Let breadth be x m.
Then, the length = 2x m
Area of rectangle=l*b
800=x*2x
800=2x²
400=x²
20m=x
Therefore, breadth=20m
Length=(2*20)m=40m

YES ITS POSSIBLE TO DESIGN A RECTANGULAR MANGO GROOVE WHOSE LENGTH IS TWICE THE BREADTH AND WHICH THE AREA IS EQUAL TO 800m^2 ...........
LET BREADTH = X m
THEREFOR LENGTH = 2X m
GIVEN , AREA=800 m^2
AREA = LENGTH * BREADTH
=X * 2X
=2X^2
800m^2=2X^2
WE GET X=20 m
therefore LENGTH= 40m
BREADTH=20m
LET BREADTH = X m
THEREFOR LENGTH = 2X m
GIVEN , AREA=800 m^2
AREA = LENGTH * BREADTH
=X * 2X
=2X^2
800m^2=2X^2
WE GET X=20 m
therefore LENGTH= 40m
BREADTH=20m
