A square rug has an area 64 ftsquared. Write the side length as a square root. Then decide if the side length is a rational number.

The area of a square can be calculated by taking the square of the side length. In this case, the area is 64 ft^2. So, we can write this as:

Side length^2 = 64 ft^2

Taking the square root of both sides gives:

Side length = √64 ft = 8 ft

So, the side length of the square rug is 8 ft.

Since the side length is a whole number, the side length of the square rug is a rational number.
