To find the perimeter of a square, we use the formula:
\[ \text{Perimeter} = 4 \times \text{side length} \]
Given the side length is \( \sqrt{212} \), we can substitute this value into the formula:
\[ \text{Perimeter} = 4 \times \sqrt{212} \]
Next, we can simplify \( \sqrt{212} \):
\[ \sqrt{212} = \sqrt{4 \times 53} = \sqrt{4} \times \sqrt{53} = 2\sqrt{53} \]
Now substituting back into the perimeter formula:
\[ \text{Perimeter} = 4 \times 2\sqrt{53} = 8\sqrt{53} \]
Thus, the perimeter of the square is:
\[ \boxed{8\sqrt{53}} \]
Please note that this answer does not match any of the provided options, which may indicate a misunderstanding. However, based on the calculations, the correct simplest radical form for the perimeter given the side length is indeed \( 8\sqrt{53} \).
