The work done is equal to the area under the curve.

*x* = 12.0 m to *x* = 18.0 m refers to triangle CDE.

The force acting on a particle varies as in the figure below. (The *x* axis is marked in increments of 1.50 m.)

Find the work done by the force as the particle moves from *x* = 12.0 m to *x* = 18.0 m
