Population = Area × Density
Area of Town A = 600 km.²
Area of Town B = 400 km.²
Total area = 600 + 400 = 1,000 km.²
Population density of Town A = 12 people / km.²
Population density of Town B = 20 people / km.²
Population of Town A = 600 × 12 = 7,200 people
Population of Town B = 400 × 20 = 8,000 people
Total population = 7,200 + 8,000 = 15,200 people
Total population density = Total Population / Total area
Total population density = 15,200 / 1,000
Total population density = 15.2 ≈ 15 people / km.²
Hope this helps

Town A population is 600 x 12 =7200
Town B population is 400 x 20 = 8000
Combined density would be 15200/1000 = 15.2 person per sq km.
Answer : 15 person per sq km

Town A=600/12=50
Town B=400/20=20

Final combined density is (how many people)/(total area).
Total how many people = 600*12 + 400*20, units are "people".
Total area = 600 + 400, unit is square kilometers.
Population density combined of those two towns = (600*12+400*20)/(600+400)
=(7200+8000)/1000
=15200/1000
=about 15 people per km squared

population of town a = 600*12 =7200
population of town b = 400*20 = 8000
population density of town a & b = 15200 / 32
