Question

The area if a square is 82.2 cm what is the side length of the square

Answer 1

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:

Therefore, the side length is 9.1 cm.
