Population Density
The population density is 3 per square kilometers
Explanation:
Population density is defined as population divided by total land area or water volume, as appropriate. An Arizona desert measures 50 square kilometers. A botanist recorded that there are 150 Saguaro cactus plants within the desert boundaries.
So the population density will be 150 divided by 50 which will be 3 per square kilometers
Hence the population density is 3 per square kilometers
