Question

question 11 (multiple choice worth 1 points)
(05 03 mc)
a county is in the shape of a rectangle that is 60 miles by 70 miles and has a population of 50,000. what is the average number of people living in each square mile of the county? round your answer to the nearest whole number
o 12
o 14
o 10
o 122

Explanation:

Step1: Calculate the area of the county

The area \(A\) of a rectangle is given by \(A = length\times width\). Here, \(length = 70\) miles and \(width=60\) miles. So, \(A=70\times60 = 4200\) square - miles.

Step2: Calculate the population density

Population density \(D=\frac{population}{area}\). The population \(P = 50000\) and the area \(A = 4200\) square - miles. Then \(D=\frac{50000}{4200}\approx11.9048\). Rounding to the nearest whole number, we get \(D\approx12\).

Answer:

12
