type the correct answer in the box. use numerals instead of words. the shape of a township with a population of 12,620 people is shown. what is the population density to the nearest tenth? the population density is approximately people per square mile.

Answer

Explanation:

Step1: Calculate the area of the township

The township can be divided into two rectangles. The first rectangle has dimensions 40 mi by (60 - 25)=35 mi, and the second has dimensions 25 mi by (40 + 25)=65 mi. The area of the first rectangle $A_1=40\times35 = 1400$ square - miles. The area of the second rectangle $A_2=25\times65 = 1625$ square - miles. The total area $A = A_1+A_2=1400 + 1625=3025$ square - miles.

Step2: Calculate the population density

Population density $D=\frac{\text{Population}}{\text{Area}}$. Given population = 12620 people and area $A = 3025$ square - miles. $D=\frac{12620}{3025}\approx4.2$ people per square mile.
