Answer:

S  = √A

Step-by-step explanation:

  Given that;

        A = S²

Finding S implies making S the subject of the expression.

 To do this;

       A = S²  

      Take the square root of both sides of the expression;

   

   √A = √S²

  The square-root of the square of S = S;

    S  = √A
