What happens to the work done if the displacement is doubled while the force remains the same?

The figure shows how the displacement of an object in the direction of a force applied varies with the force. The shaded area under the graph represents:

If a force of 30 N moves an object 4 meters, what is the work done?
What is the work done by a 20 N force over a distance of 10 meters?
A force of 20 N acts on an object in the direction of displacement, and the object moves a distance of 10 meters. What is the work done?
