1 Multiply the perimeter by the ceiling height to get the total wall area: 50 ft. x 8 ft. = 400 sq. ft. 2  Doors are usually 21 square feet (there are two in this exercise): 21 sq. ft. x 2 = 42 sq. ft.  Windows average 15 square feet (there are two in this exercise): 15 sq. ft. x 2 = 30 sq. ft.
The covering is to be hung in a 12-foot by 15-foot room with an 8-foot ceiling, one standard door, and two standard windows. Add the length and width of the room together and double it. (12 + 15 = 27 x 2 = 54) Multiply the answer from step 1 by the ceiling height. (54 x 8 = 432 sq. ft.) Determine the square feet of windows and doors in the surface to be covered - 20 sq. ft. for each standard size window or door. ( 20 x 3 = 60)
