To find the length of a side of the square field, we need to find the square root of its area. The square root of 479 is approximately 21.9.
Since the length of a side cannot be a decimal, we need to round our answer to the nearest foot.
Rounding 21.9 to the nearest whole number gives us 22.
Therefore, the approximate length of a side of the field is 22 feet.
A square field has an area of 479 ft2. What is the approximate length of a side of the field? Give your answer to the nearest foot. Explain your response.
