हिन्दीEach side of a thin square sheet is measured to be \( 4.12\text{ m} \). The surface area of the square sheet, reported to the correct number of significant figures, is:
Correct answer · Option 3
\( 17.0\text{ m}^2 \)
Explanation
The side has 3 significant figures. Calculated area \( = (4.12)^2 = 16.9744\text{ m}^2 \). Rounding to 3 significant figures gives \( 17.0\text{ m}^2 \).
