NEED HELP ASAP SOMEONE PLEASE!!!!
Alisiya [41]

Answer: The state with the second lowest population has the lowest population density.

Step-by-step explanation:

Since, Density = Population / Area

The population of state A = 1,055,173

Its area = 2677 square km

Thus, the density of state A = \frac{1055173}{2677} = 394.162495,

The population of state B = 1,333,089

Its area = 36,418 square km

Thus, the density of state B = \frac{1,333,089}{36,418} = 36.6052227,

The population of state C = 3,596,677

Its area = 5543 square km

Thus, the density of state C = \frac{3,596,677}{5543} = 648.868302,

The population of state D =6,745,408

Its area = 10555 square km

Thus, the density of state D = \frac{6,745,408}{10555} = 639.072288,

Since, by the above explanation,

The state in increasing order of the populations,

State A < State B < State C < State D,

Also, the state in increasing order of density,

State B < State A < State D < State C

⇒ Second option is correct.
