To find the side length of a square given its area, you can use the formula for the area of a square:
\[ \text{Area} = \text{side length}^2 \]
Given that the area is 48 sq meters, you can set up the equation:
\[ \text{side length}^2 = 48 \]
To find the side length, take the square root of both sides:
\[ \text{side length} = \sqrt{48} \]
Calculating the square root:
\[ \sqrt{48} \approx 6.93 \]
Rounding to the nearest meter, this is approximately 7 meters.
Among the options provided (6, 12, 7, 24), the closest measurement to the side length of the square is 7 meters.
