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 approximate length of a side of the square field, we need to take the square root of the area.
√479 ≈ 21.88.
Since the question asks for the answer to the nearest foot, the approximate length of a side of the square field is 22 feet.
To find the length of a side of the square field, we can use the formula for the area of a square:
Area = side^2
Given that the area is 479 ft^2, we can set up the equation as:
479 = side^2
Next, we can solve for the side length by taking the square root of both sides of the equation:
√479 = √(side^2)
√479 = side
Evaluating the square root of 479, we find that it is approximately 21.9089. Since we are looking for an approximate value to the nearest foot, we can round this to the nearest whole number. Therefore, the approximate length of a side of the field is 22 feet.
