Step-by-step Solution
To find the length of one side of a square when you know the area, you can use the formula for the area of a square:
\[
\text{Area} = \text{side}^2
\]
Given that the area of the square is \( 121 \, \text{cm}^2 \), you can set up the equation:
\[
\text{side}^2 = 121
\]
To find the length of one side, take the square root of both sides:
\[
\text{side} = \sqrt{121}
\]
Calculating the square root:
\[
\text{side} = 11 \, \text{cm}
\]
Thus, the length of one side of the card is \( 11 \, \text{cm} \).
Quick Answer
The length of one side of the card is \( 11 \, \text{cm} \).
