Answer:

work done will be equal to 305.05 J

Explanation:

We have given force exerted F = 45 N

Angle with the horizontal $\Theta =41^{\circ}$

Distance moved due to exerted force d = 9.1 m

Work done is equal to $W=Fcos\Theta \times d$ , here F is force $\Theta$ is angle with horizontal and d is distance moved due to force

So work done $W=45\times cos41^{\circ}\times 9.1=309.05J$

So work done will be equal to 305.05 J
