To find the length of the square room, we can use the formula for the area of a square.
The formula for the area of a square is given by:
Area = side length^2
In this case, we are given that it took 81 ft2 to carpet the room. We need to find the length of the room.
Let's set up the equation using the given information:
81 ft^2 = side length^2
To solve for the side length, we take the square root of both sides of the equation:
√(81 ft^2) = √(side length^2)
Calculating the square root:
9 ft = side length
Therefore, the length of the square room is 9 feet.
