conversations.value: Can you guide me through solving this problem: 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?

conversations.value: The solid wall is 8 ft. * 20 ft. = 160 sq. ft.
  The doorway is 3 ft. * 7 ft. = 21 sq. ft.
  The window is 6 ft. * 4 ft. = 24 sq. ft.
  The closet door is 5 ft. * 7 ft. = 35 sq. ft.
  The total area of the doors and windows is 21 sq. ft + 24 sq. ft. + 35 sq. ft. = 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. = 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. = 560 sq. ft.
