Answer to Problem 34PPE
Centimeter is the most appropriate measurement for measuring the poster as a poster size is within the range of a few meters dimensions only, so it is better to use centimeter.
Explanation of Solution
Given information:
A poster hanging on the wall and three units meters, centimeters and millimeters.
Formula/Concept used:
Meter is used to measure dimensions of larger objects. Centimeter is best used to measure the dimensions that are under 1 meter or a few meters range. And millimeter is used to measure the smallest dimensions or to measure very small gaps.
Conclusion:
As, the length and width of a poster on the wall are with one meter or a few meters range, it is well suitable to use centimeters for its measuring.
b)
To find:
The unit of measure that is most accurate, on measuring a wall poster in centimeters, meters and millimeters.

Answer to Problem 34PPE
Measuring in millimeters will give the most accurate results that will be free of any precision error etc.
Explanation of Solution
Given information:
A poster hanging on the wall and three units meters, centimeters and millimeters.
Formula/Concept used:
Meter is used to measure dimensions of larger objects. Centimeter is best used to measure the dimensions that are under 1 meter or a few meters range. And millimeter is used to measure the smallest dimensions or to measure very small gaps.
Conclusion:
As very small gaps can be ignored in using centimeter and meter, it is always used millimeter to measure to maximum accuracy.
