If \( A = 121 \, \text{ft}^2 \) represents the area of a square, the length of each side can be found using the formula for the area of a square:

\[
A = s^2
\]

where \( s \) is the length of each side. To find \( s \), take the square root of the area:

\[
s = \sqrt{A} = \sqrt{121} = 11 \, \text{ft}
\]

So, the length of each side is 11 feet.
