To write:the metric unit of length for the given objects.

Answer to Problem 44P
The height of room should be measured in meters.
Explanation of Solution
Given:
Height of a room
Calculation:
There are 2 systems for measurement, one is customary system and other is metric system.
Customary has been used historically for various measurements, while metric system is widely accepted due to ease of calculations.
Various units of length in metric system are millimeters, centimeters, meters, kilometers, etc.
Since, room heights vary from place to place and are not very small nor very large but are of intermediate nature. Such things like door height, width of road are usually measured in meters.
Thus, it is reasonable to say that height of room should be measured in meters.
Conclusion:
Hence, the height of room should be measured in meters.
