We know that the area of a square is 49 square meters.

The area of a square is defined by

[tex]A=l^2[/tex]

Where l is the length of each side.

Replacing the given are, we have

[tex]\begin{gathered} 49=l^2 \\ l=\sqrt[]{49} \\ l=7 \end{gathered}[/tex]

Therefore, the side length is 7 meters long.
