Answer 1

Option C:
`$ \sqrt{\textbf{121}} $`

Explanation:

Given the side length of a square is 11 units.

Note that
`$ √(121) = \pm 11 $`

Since, length cannot be negative, we can eliminate - 11.

Hence, the length of the side of the square is 11 units =
`$ √(11^2) = √(121) $`.

Hence, the answer.
