.

In this problem, the work done is the product of the distance and the horizontal component of the force.

The distance is 153 m horizontally.
The horizontal component of the force is 225*cos(65°) newtons.

Thus the work is 153*225*cos(65°) newtons*meter = 153*225*cos(65°) joules.

I leave computations to you.

Solved.
