Answer: Based on the information given in the problem, we know that the width of the outer region of the rug is 4 inches. It is not specified what the width of the inner square is, but we do know that its side length is x inches.
Therefore, it is incorrect to say that the width of the rug is 4 feet, as the problem specifies the width in inches. However, if we convert the width to feet, we can say that the width of the outer region is:
4 inches = 4/12 feet = 1/3 feet
So we can say that the width of the outer region is 1/3 feet. However, we should be careful not to confuse the units of measurement. We cannot say that the width is both 4 inches and 4 feet, as these are two different units of measurement.
