The area of a 2D form is the amount of space within its perimeter. The area of one of the walls of the square room is 15 meters².
What is an area?
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Given that the square room has a floor area of 25 square meters. Therefore, the length of the square floor will be,
Area of square floor = Area of square
25 meter² = a²
a = 5 meter
Now, as it is given that the height of the room is 3 meters. Therefore, the area of a single wall of the room is,
Area of wall = Length of the side × Height of the Wall
= 5 meters × 3 meters
= 15 meters²
Hence, the area of one of the walls of the square room is 15 meters².
