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 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.
To find the approximate length of a side of the square field, we can use the formula for the area of a square. The formula for the area of a square is A = s^2, where A is the area and s is the length of a side.
In this problem, we are given that the area of the square field is 479 ft^2. To find the length of a side, we can rearrange the formula to solve for s:
s = √A
Substituting the given area of 479 ft^2 into the formula, we have:
s = √479
Now, we can use a calculator or math software to find the square root of 479:
s ≈ 21.92
Therefore, the approximate length of a side of the square field is 22 feet (rounded to the nearest foot) based on the calculated value of s.
To find the length of a side of a square field, we need to calculate the square root of its area. Given the area of the field is 479 ft^2, we can find the length of a side by taking the square root of 479.
Here's how to do it step by step:
1. Take the square root of the area: √479 ≈ 21.88.
2. Round the result to the nearest foot: 22.
Therefore, the approximate length of a side of the square field is 22 feet.
