Answer:
L*W
Step-by-step explanation:
As we Know tha area of a rectangle is Leght*witdth so in this case will be L*W but lets prove it by calculating the integral:
Area= L*W=
So as the integral of a constant is the constant multiplied by the integration variable x.
The integral becomes: L*W(x) where W(x) in this case is W= L*W
Good luck!
