A square field has an area of 479 ft squared. What is the approximate length for a side of the field? Give your answer to the nearest foot. Explain your response.

22 ft

Step-by-step explanation:

To find the length of the side of a square you need to do the opposite equation for finding area.

So the equation for finding the area of a square is a - x^2, or a = x squared.

The opposite of this equation would be x = square root of 479 because the opposite operation of squared is square root.

Now you need to solve this equation

So x = square root of 479, the square root of 479 is 21.89

So the x equals 21.89 but you need to find the approximate length so you need to round. It says to round to the nearest foot so one side of the square is 22 feet long.
