For this case we have the following equation:
w = || F || • || PQ || costheta
Where,
|| F ||: force vector module
|| PQ ||: distance module
costheta: cosine of the angle between the force vector and the distance vector.
Substituting values:
w = (60) * (100) * (cos (45))
w = 4242.640687 lb.ft
Answer:
The work done pushing the lawn mower is:
w = 4242.640687 lb.ft
Answer:
Yes, because the area of one side of the divider is approximately 24ft^2

Sample 1:
Error = 14 - 13.7 = 0.3
Percentage Error = 0.3/13.7 x 100 = 2.19%
Sample 2:
Error = 24.4 - 24 = 0.4
Percentage Error = 0.4/24.4 x 100 = 1.64%
Sample 3:
Error = 25.8 - 25 = 0.8
Percentage Error = 0.8/25.8 x 100 = 3.1%
Sample 4:
Error = 40.2 - 39 = 1.2
Percentage Error = 1.2/40.2 x 100 = 2.99%
Sample 2 has the least percent error
