     Matrix A below gives the fraction of the earth\'s area and the projected fraction of its population for five continents in 2050. Matrix B gives the earth\'s area (in square miles) and its projected 2050 population.  A = [Fraction of Area 0.162 0.119 0.066 0.298 0.202  Fraction of Population 0.047 0.086 0.065 0.582 0.215]  North America South America Europe Asia Africa  B = [Area 57, 850,000 0  Population 0 9, 322,000,000]  Area Population  Find the area (in square miles) and population of each given continent by finding AB.    

 
  
  Solution
On multiplication, we have AB =
9371700
438134000
6884150
801692000
3818100
605930000
17239300
5425404000
11685700
200423000
Thus, the area in Sq. miles and the population of the given continents are as under:
Continent
Area (sq. miles)
Population
North America
9371700
438134000
South America
6884150
801692000
Europe
3818100
605930000
Asia
17239300
5425404000
Africa
