The length and breadth of a rectangular sheet are \(16.2\) cm and \(10.1\) cm, respectively. The area of the sheet in appropriate significant figures and error would be, respectively,
1. \(164\pm3~\text{cm}^2\)
2. \(163.62\pm2.6~\text{cm}^2\)
3. \(163.6\pm2.6~\text{cm}^2\)
4. \(163.62\pm3~\text{cm}^2\)
The measure of two quantities along with the precision of respective measuring instrument is . The value of AB will be:
1. (0.25 0.08) m
2. (0.25 0.5) m
3. (0.25 0.05) m
4. (0.25 0.135) m
You measure two quantities as A = 1.0 m 0.2 m, B = 2.0 m 0.2 m. We should report the correct value for as
1. 1.4 m 0.4 m
2. 1.41 m 0.15 m
3. 1.4 m 0.3 m
4. 1.4 m 0.2 m
