Find one side of the square in simplest radical form

The area of a square is 60 square inches. What is the length of one side? I’m not allowed round. ​

If you are not allowed to round, the only other way to go is simplest radical form.

Area of a square = s²   {one side, squared}
s² = 60   {substituted 60, in for area, into area formula}
s = ±√60   {took square root of each side}
s = ± √4 √15   {broke down the square root of 60}
s = ± 2√15   {evaluated square root of 4} 

The side of a square cannot be negative. 

s = 2√15   {one side of the square, in simplest radical form}
