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
Step-by-step explanation:
a) Since,![Density = \frac{Population}{Area}](/tpl/images/0019/3404/4edd0.png)
Here, The population of New York = 19,795791
Area = 47126
Thus, the Density of the New York
=![\frac{19,795791}{47126} =420.060921784\approx 420](/tpl/images/0019/3404/9dc33.png)
Similarly, Density of Maryland,
=![\frac{6,006,401}{9,707}= 618.770062841\approx 619](/tpl/images/0019/3404/b10a2.png)
And, Density of Pennsylvania
=![\frac{12,802,503}{44,743}= 286.134210938\approx 286](/tpl/images/0019/3404/616a7.png)
b) Since, 619 > 420 > 286
Thus, the states in the decreasing order of their density,
Maryland, New York, Pennsylvanian
