Final answer:

To find the wall area excluding the windows and the door, subtract the combined area of both (6m² for windows and 5m² for the door) from the total wall area of 220m², resulting in 209m².

Step-by-step explanation:

The area of the walls of a room with two windows and a door can be found by subtracting the combined areas of the windows and the door from the total wall area. Here, the total area of the walls is 220 square meters, each window has an area of 3 square meters, and the door has an area of 5 square meters. Since there are two windows, we multiply the area of one window by 2 to get the total window area. Then, we add the area of the door. Finally, we subtract this combined area of windows and door from the total wall area to find the area of the walls excluding the windows and the door.

  1. Calculate the total area of the windows: 3m2 per window × 2 windows = 6m2.
  2. Add the area of the door: 6m2 + 5m2 (door) = 11m2.
  3. Subtract the combined area of windows and door from the total wall area: 220m2 - 11m2 = 209 square meters.

Therefore, the area of the walls excluding the windows and doors is 209 square meters.
