Question

The population and area of three U.S. states in the East Coast region are given:

State Population (2015) Area (Sq. Miles)

New York 19,795,791 47,126

Maryland 6,006,401 9,707

Pennsylvania 12,802,503 44,743


a) Find the population density of the three states, rounded to the nearest whole person.

b) Rank the three states from Most densely populated state to least densely populated state.

Answer 1

Answer: a) Density of,

New York = 420

Maryland = 619

Pennsylvanian = 286

b) The required order from most dense state to least dense state is,

Maryland, New York, Pennsylvanian

Explanation:

a) Since,
`Density = (Population)/(Area)`

Here, The population of New York = 19,795791

Area = 47126

Thus, the Density of the New York

=
`(19,795791)/(47126) =420.060921784\approx 420`

Similarly, Density of Maryland,

=
`(6,006,401)/(9,707)= 618.770062841\approx 619`

And, Density of Pennsylvania

=
`(12,802,503)/(44,743)= 286.134210938\approx 286`

b) Since, 619 > 420 > 286

Thus, the states in the decreasing order of their density,

Maryland, New York, Pennsylvanian
