We are given the area of a square and we are asked to find its side length. To do that, let's remember the formula for the area of a square:


A=l^2

Where:


\begin{gathered} A\colon\text{ Area} \\ l\colon\text{ side length} \end{gathered}

We solve for the side length "l", by taking square roots on both sides:


\sqrt[]{A}=l

Since we are given that the area is:


A=82.2cm^2

Replacing:


\sqrt[]{82.2}=l

Solving the operations:


9.1\operatorname{cm}=l

Therefore, the side length is 9.1 cm.
