Based on the given dimensions, the area of one wall in the square room is 45 square meters
How to determine the area of one wall?
From the question, the given parameters about the square room are:
Floor area = 81 square meters
Height of the room = 5 meters
The area of a square is calculated using
Area = Length * Length
This means that:
Floor area = Floor length * Floor length
Substitute the known values in the equation
81 square meters = Floor length * Floor length
Rewrite the equation as:
81 square meters = Floor length^2
Take the square root of both sides
Floor length = 9 meters
The area of one wall is then calculated as:
Area of one wall = Floor length * Height of the wall
So, the equation becomes
Area of one wall = 9 meters * 5 meters
Evaluate the product
Area of one wall = 45 square meters
Hence, the area of one wall in the square room is 45 square meters
