Longest possible length with the appropriate level of precision for a measurement of 34.2
Answers

The number 34.2 is expressed with three significant figures. If you want to express the longest possible length with the same level of precision, you could include additional zeros after the decimal point, but it should preserve the level of precision implied by the original measurement.
Thus, the longest possible representation while maintaining three significant figures would be 34.200. This expression retains the same precision as 34.2 and indicates that the measurement is precise to the hundredths place.

To determine which option has the closest precision to the measurement of 34.2 (which has three significant figures), we need to choose the option that is expressed with three significant figures.
Here’s a breakdown of the options based on the number of significant figures:
1. **29.2** - 3 significant figures
2. **35.25** - 4 significant figures
3. **33.7** - 3 significant figures
4. **34.25** - 4 significant figures
The options that have **three significant figures** and are closest to the precision of the measurement 34.2 are:
- **29.2**
- **33.7**
However, only **33.7** closely approaches the measurement of 34.2.
So, the best answer is **33.7**.
