A force of 2 newtons acts through 3 meters in the direction of the force. What is the work done?

Work is the energy transferred when a force moves an object through a distance in the same direction as the force. When the force points exactly along the motion, the work is simply W = F × d. Here, the force is 2 newtons and the object moves 3 meters in the same direction as that force, so the work done is 2 × 3 = 6 joules. If the force weren’t aligned with the motion, you’d use W = F × d × cos(theta) to account for only the component in the direction of motion.
