The length and breadth of a metal sheet ...

The length and breadth of a metal sheet are 2.325 m and 3.142 m respectively. What is the area of this sheet using proper number of significant figures?

A

`7.30515m^(2)`

B

`7.3051m^(2)`

C

`7.305m^(2)`

D

`7.31m^(2)`

Text Solution

Verified by Experts

The correct Answer is:
c
Area = `Lxxb=2.325xx3.142=7.30515m^(2)`
L and b have four significant figures. Hence rounding off the number 7.30515 to four significant figures, we get the area of the sheet = `7.305m^(2)`
