Your bathroom floor is a square with side lengths of 9 feet. (Area = s^2)
A contractor is tiling your bathroom with one-foot square tiles. How many tiles are needed for the job?
Step-by-step explanation: It is given that the side lengths are all 9 feet. Since the bathroom is a square, all the sides of the bathroom are 9 feet. You can use the formula (area = s^2). 9 x 9 is 81.
