W = Fâscosθ where θ is the angle between force and direction of motion.
If the force is to the left, + 125 ft.lbs
If the force is to the left, - 125 ft.lbs
If the force is to the vertical, 0 ft.lbs

By definition, work is equal to force x distance. So, for your problem,
W = Fd
W = 25 * 5
W = 125 ft-lbs
