Answer:

$People\ per\ square\ mile\approx 27539$

Step-by-step explanation:

World's Population$=7.4\ billion=7.4\times 10^9=7400000000$

Area of state$=268712\ square\ miles$

$People\ per\ square\ mile=\frac{total\ population\ in\ that\ area}{total\ area\ of\ the\ state}\\\\Here\ world's\ population\ is\ put\ in\ that\ state\\\\ So\ population\ in\ that\ state=7.4\ billion\\\\People\ per\ square\ mile=\frac{7400000000}{268712}\\\\People\ per\ square\ mile=27538.77\approx 27539$
