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]
