Answer:
Option C: [tex]$ \sqrt{\textbf{121}} $[/tex]
Step-by-step explanation:
Given the side length of a square is 11 units.
Note that [tex]$ \sqrt{121} = \pm 11 $[/tex]
Since, length cannot be negative, we can eliminate - 11.
Hence, the length of the side of the square is 11 units = [tex]$ \sqrt{11^2} = \sqrt{121} $[/tex].
Hence, the answer.
