Answer:

12.5698 (approximately 12.5, rounding to the nearest half)

Step-by-step explanation:

The area of a square is represented by the following equation:

[tex]A=a^2[/tex]

Whereas "a" represents the length of any one of the sides.

Since all sides of a square are equal in length, we can reverse engineer this formula to find the length of one side.

[tex]158=a^2[/tex]

Simply take the square root of both sides and you will have your answer.

[tex]12.5698=a[/tex]
