The length and breadth of a metal sheet are 3.124 m and 3. 002 m respectively. The area of this sheet up to the correct number of significant figures is
Text Solution
Verified by ExpertsThe correct answer is:
A
9 .378 m 2
Area of metal sheet = 3 .124 x3 .002 m 2 = 9 .378248 m
2
Now, the result must have significant figures equal to the least of figures being multiplied, so, area of metal sheet = 9 .378 m 2 (four significant digits)
