HELLO THERE!
 
According to me, 
 
Let the angle of inclination of the inclined plane be \Theta
Length of the inclined plane = L.
So, base component = Lcos\Theta
 
Force is Horizontal, so Force = F (the given term itself).
 
So, Work done = Force x Displacement
= F Lcos\Theta
 
[The mass of the body is given just to confuse you].
