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.
To find the length of a side of the square field, we need to find the square root of the area.
By taking the square root of 479, we get approximately 21.9. Since we are looking for the length of a side of the field, we will round this to the nearest foot, which is 22 feet.
So, the approximate length of a side of the square field is 22 feet.
