Answer 1

The area of a square is given by the following expression:

`A=l^2`

Where A is the area of the square, while l is the length of the side. The problem informed us of the area of the square, therefore we can use that value for A and solve the expression for l, we have:

`\begin{gathered} 98=l^2 \\ l=\sqrt[]{98} \\ l=9.899 \end{gathered}`

The length of the side is approximately 9.9 m
