In a basement renovation, the contractor measured the length of a wall in a square room as 18ft.4in. The width of the doorway is 3 ft. The contractor plans to place wood trim along the bottom of each wall. The trim costs 1.69/ft. What is the cost of the trim for the room, before taxex?

The way it stands:
4 times the length of 18 ft, 4 inches, then subtract 3 ft for the doorway.
Multiply that by 1.69

more realistic:
Will there be any cut-off waste ?
What happens it you can only buy the trim in 8 ft lengths?

This question is much too simplistic.
