हिन्दीThe area of a rectangular field (in \( \text{m}^2 \)) of length \( 55.3\text{ m} \) and breadth \( 25\text{ m} \) after rounding off the value for correct significant digits is:
Correct answer · Option 2
\( 14 \times 10^2 \)
Explanation
Area = \( 55.3 \times 25 = 1382.5\text{ m}^2 \). Since breadth has 2 significant figures, the result must be rounded to 2 significant figures, giving \( 14 \times 10^2\text{ m}^2 \).
