maria is using a meter stick to determine the height of a door. if the smallest unit on the meter stick is centimeters, which measurement could maria have used to most accurately record the height of the door? 2 meters 2.31 meters 2.3 meters 2.309 meters
Answer
# Explanation:
## Step1: Understand measurement precision
The meter - stick has centimeters as the smallest unit. 1 meter = 100 centimeters. Measurements should be recorded to the precision of the measuring tool.
## Step2: Analyze each option
- 2 meters is too general as it doesn't use the centimeter - level precision.
- 2.3 meters is to the nearest tenth of a meter, not using the full centimeter precision.
- 2.31 meters is to the nearest hundredth of a meter. Since 0.01 meters = 1 centimeter, this is the most accurate measurement given the meter - stick's precision.
- 2.309 meters implies a precision smaller than a centimeter (millimeter - level precision as 0.001 meters = 1 millimeter), which is not possible with the given meter - stick.
# Answer:
2.31 meters
