The floor would be horizontal
The applied force and the displacement are in the same direction ... parallel to the floor
so use W = Fd
W = 5 * 3
W = 15 J
... the weight of the object (20 N) acts vertically down ... so it's at right angles to the applied force and doesn't affect the work done by you
