#F2# is irrelevant because it is at right angles to the direction of motion. Vector addition of #F1# and #F3# yields a net force of #10# #N# to the right.

#W=Fd=10xx3=30# #J#

Explanation:

The work done is the product of the net force acting and the distance travelled (in the direction of the net force), #W=Fd#.
