Final answer:
The area of the four walls of the room is 0 square meters.
Step-by-step explanation:
The perimeter of a rectangular room can be calculated by adding up the lengths of all four sides. In this case, the perimeter is given as 26 meters. Since the height of the room is 5 meters, we can divide the perimeter by 2 to find the sum of the lengths of the two longer sides. This gives us 26/2 = 13 meters. So, the lengths of the two longer sides are each 13 meters.
Now, let's find the lengths of the two shorter sides. The total length of all four sides is equal to 2 times the sum of the lengths of the two shorter sides. We can subtract the lengths of the two longer sides from the total length to find the sum of the lengths of the two shorter sides. This gives us 26 - 2(13) = 0 meters. So, the sum of the lengths of the two shorter sides is 0 meters.
Since the sum of the lengths of the two shorter sides is 0, it means that the lengths of the two shorter sides are also 0. Therefore, the area of the four walls of the room is 0 square meters.
