Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Ukuta wa kawaida una eneo la futi 8 * futi 20 = <<8*20=160>>160 sq. ft.
Mlango una eneo la futi 3 * futi 7 = <<3*7=21>>21 sq. ft.
Dirisha lina eneo la futi 6 * futi 4 = <<6*4=24>>24 sq. ft.
Mlango wa kabati una eneo la futi 5 * futi 7 = <<5*7=35>>35 sq. ft.
Jumla la eneo la milango na dirisha ni 21 sq. ft + 24 sq. ft. + 35 sq. ft. = <<21+24+35=80>>80 sq. ft.
Ukuta wa kawaida una eneo la 160 sq. ft., hivyo kabla ya kuzingatia eneo la milango na dirisha, jumla la eneo la ukuta ni 4 * 160 sq. ft. = <<4*160=640>>640 sq. ft.
Kwa kuzingatia milango na dirisha, jumla la eneo la ukuta ambalo Linda atalazimika kupaka rangi ni 640 sq. ft. - 80 sq. ft. = <<640-80=560>>560 sq. ft.
