The area of a square is computed as:
Area=s^2
We substitute the area with 9 sq m
s^2=9m^2 \\ s= \sqrt{9m^2} =3m

Therefore the side length of the square room is 3 meters.

The formula for the area of the square:
A=s²

Substitute the given measurement:
9 m²=s²
Square root both sides
s=3 m

We cannot say s=-3 m because there is no negative length. Hope this helps =)
