Linda is painting her bedroom. Her bedroom has 4 walls, with the room being 20 feet wide by 20 feet long by 8 feet tall. One wall has a 3-foot by 7-foot doorway. A second wall has a 6-foot by 4-foot window. A third wall has a 5-foot by 7-foot doorway to a walk-in-closet. And the fourth wall is completely solid. What is the total area of wall space that Linda will have to paint?
The solid wall is 8 ft. * 20 ft. = <<8*20=160>>160 sq. ft.
The doorway is 3 ft. * 7 ft. = <<3*7=21>>21 sq. ft.
The window is 6 ft. * 4 ft. = <<6*4=24>>24 sq. ft.
The closet door is 5 ft. * 7 ft. = <<5*7=35>>35 sq. ft.
The total area of the doors and windows is 21 sq. ft + 24 sq. ft. + 35 sq. ft. = <<21+24+35=80>>80 sq. ft.
The solid wall is 160 sq. ft., so before the areas of the doors and window are taken into account, the total wall area is 4 * 160 sq. ft. = <<4*160=640>>640 sq. ft.
Taking into account the doors and window, the total wall area Linda will have to paint is 640 sq. ft. - 80 sq. ft. = <<640-80=560>>560 sq. ft.
