If every positive number has two square roots, and you can find the length of the side of a square window by finding a square root of the area, why is there only one answer for the length of a side?

One root is positive and the other is negative. There is no negative length :)

Every positive number has two square roots, but when calculating physical dimensions like the length of a side of a square window, we only use the positive square root because lengths cannot be negative. For example, the square root of 16 is 4, representing the length of the side. Therefore, the only answer for length in this scenario is the positive square root.
