To answer, it is assumed that the building is rectangular so that the perimeter is twice the sum of the dimensions given.

Perimeter = 2 x (length + width)

= 2 x (120 ft + 100 ft) = 440 ft

We multiply this by the given cost per foot to determine the total cost of the job.

Total cost = (440 ft) ($0.10/ft)

= $44

Thus, the answer is $44.
