The us census found at the population per square mile in the state rose from 128.7 to 191.3 during the last 10 years. by how much did the population grow per square mile

62.6 per square mile.

Step-by-step explanation:

The U.S. Census found at the population per square mile in the state rose from 128.7 to 191.3 during the last 10 years.

Population at initial year = 128.7

Population after 10 years = 191.3

Population grow per square mile = 191.3 - 128.7

                                                       = 62.6 per square mile.

Population grew 62.6 per square mile.

answer is more than one

step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
