If a square room has a floor with an area of 289 square feet, how long is each side of the floor?
To find the length of each side of the floor, we need to take the square root of the area.
Given that the area is 289 square feet, the length of each side of the floor is the square root of 289.
√289 = 17
Therefore, each side of the floor is 17 feet long.
