How much greater is the population density of Manhattan than that of New York City?​

Answer 1

Answer:

42,804.35 million people per miles

Step-by-step explanation:

Population density = Number of people / Land area

New York

Population = 8.55 million

Land area = 300 square miles

Manhattan

Population = 1.64 million

Land Area = 23 Square miles

Population density of New York = Number of people / Land area

= 8.55 million / 300 Square miles

= 8,550,000 / 300

= 28,500 people per square miles

Population density of Manhattan = Number of people / Land area

= 1.64 million / 23 miles

= 1,640,000 / 23

= 71,304.35 million people per square miles

Difference between Manhattan and new York City = 71,304.35 - 28,500

= 42,804.35 million people per miles

Therefore,

The population density of Manhattan is greater than that of New York City by 42,804.35 million people per miles
