Answer
W = -572 J
Work Step by Step
We can find the angle between Paul's force vector and the displacement vector.
$\theta = 61.0^{\circ}+90.0^{\circ}+22.0^{\circ}$
$\theta = 173.0^{\circ}$
We can find the work done by Paul's force.
$W = F~d~cos(\theta)$
$W = (48.0~N)(12.0~m)~cos(173.0^{\circ})$
$W = -572~J$
