Question:
How many feet of baseboard would you need to go around a rectangular room if the room has a length of 12 feet and a width of 7(1/2) feet, and you must deduct 4 feet for a doorway?
A
35
Explaination
The perimeter of the room is 2 × 12 + 2 × 7.5 = 24 + 15 = 39 feet. Subtracting 4 feet for the doorway leaves you needing 35 feet of baseboard.
