how much work is required to push a lawn mower 75 ft if the force on the handle is 65 lbs & the handle is 45°?

... if the handle makes an angle 45° from horizontal. Round to the nearest ft.-lb.

Update:

It said there was a 45° angle, so I figured it would be 65cos45°x75= approx 3497ft-lb, but according to the back of the book, the answer is 5362 ft-lb, so I'm not quite sure what I'm doing wrong
