Chapter 12.7, Problem 20E

Follow the rules for working with measurements:

An aquaculture facility is installed in a school. To take best advantage of the space, the teacher decides to construct the fish tank from concrete blocks in a corner and line the sides and bottom with heavy vinyl. The tank is in the shape of a right triangle with interior measurements of 9.00 ft, 12.0 ft, and 15.0 ft. The walls are built 3.00 ft high. The rule of thumb in projects of this sort is to order 10% more than the actual required amount in order to account for waste and overlapping. At a cost of $0.26/ ${\text{ft}}^{\text{2}}$, how much will the vinyl cost to line the interior walls and bottom?
