Final answer:
To calculate the total area of all four walls of a square room with a floor area of 16 square meters and a height of 5 meters, we find the perimeter (16 meters) and multiply it by the height, resulting in an area of 80 square meters for the walls.
Step-by-step explanation:
The question seems to contain a typo. Assuming you meant to ask about the area of all four walls in the room rather than four 'rooms', we can calculate this using the dimensions given for a single square room. Since the room is square with an area of 16 square meters, each side of the room measures 4 meters (since 4m * 4m = 16m2). To find the area of all four walls, we multiply the perimeter of the room by the height of the walls. The perimeter of the room is 4 sides each 4 meters long, which amounts to 16 meters. As the height is given as 5 meters, the total area of the four walls is 16m * 5m = 80m2.
