Hello users ....

We know that:
Area of rectangle = L × B 
where, L is length and B is breadth.

Solution:-
Let breadth of rectangle = x m 
And
length of rectangle = 2x m
(Given : length is twice its breadth)

And
Area of rectangle = 800 m²

=> L × B = 800 m²
=> (2x)×(x) = 800 
=> 2x² = 800 
=> x² = 800 / 2 = 400
=> x = 20 m 

Hence;
Length of rectangle = 2x = 2×20 = 40 m
And
breadth of rectangle = x = 20 m  Answer

Hope it helps 
:)
