The area of a square can be found using the equation A = s², where A is the area and s is the measure of one side of the square.

Match the equation for how to solve for the side length of a square to its description.

The equation given for the area, A is

A = s^2.

Then, you are asked to solve for the side, s.

You need to extract square root from both side which drives to:

√ (s^2) = + / - (√A)

=> s = + / - (√A)

but given that s is a length it can only be positive, and

s = (√A)

Answer: s = √A
