To find the approximate length of a side of the square field, we need to take the square root of the area of the field. The area of the square field is given as 479 ft².
The square root of 479 can be estimated using a calculator or using estimation techniques. By estimating, we can determine that the square root of 479 is approximately 21.9.
Since the length of a side of a square is equal to the square root of its area, the approximate length of a side of the field is 21.9 ft.
However, the question asks us to give the answer to the nearest foot, so we round our result. The number after the decimal point is 9, which is greater than or equal to 5. Therefore, we round up the length to the nearest foot.
Hence, the approximate length of a side of the field is 22 ft.
