Explain how you will find the length of one side of a square if the area is 16 square units.

To find the length of one side of the square with an area of 16 square units, we first need to know the formula for finding 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 one side.

Given that the area of the square is 16 square units, we can set up the equation as follows:
16 = s^2

To find the length of one side, we need to take the square root of both sides of the equation:
s = √16
s = 4

Therefore, the length of one side of the square is 4 units.
