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)

s = √A

Ithink the answer is a
