To find the side length of a square painting when the area is given as 81 cm², you can use the formula for the area of a square:

\[
\text{Area} = \text{side}^2
\]

Given that the area is 81 cm²:

\[
81 = \text{side}^2
\]

To find the side length, take the square root of both sides:

\[
\text{side} = \sqrt{81} = 9 \text{ cm}
\]

So, the side length of the square painting is 9 cm.
