Answer:
A reasonable measure for the height of the door would be 2.23 meters
Explanation:
We use three units of measurement in our daily life.
Centimeter, Meter and Kilometer
When comparing the three units centimeter is the smallest unit and kilometer is the largest.
1 meter= 100 cm
1 kilometer= 1000 meter= 100000 centimeter
If we measure the height of the classroom's door in centimeter which is approximately 223 cm, it is better to convert it into a unit higher than centimeter. We know that 100 cm is equal to 1 meter. So, instead of writing 223 cm it is better to write 2.23 m, neither 0.223 Km. If the number lies between 100 cm ≤number <100,000 cm, convert it into meters by dividing the number by 100, which is best unit of measurement.
