d) Find the total area of all countries listed above?
e) Order these countries from the largest to the smallest areas?

Answer 1

a) The smallest area is $242,400$ kilometers squared and it is that of the UK.
b) The largest area is $17,098,242$ kilometers squared and corresponds to Russia.
c) The difference between the areas of Russia and China is given by
$=17,098,242-9,598,094=7,500,148$ kilometers squared
d) The total area of the countries listed above is given by
$=9,629,091+17,098,242+9,598,094+9,984,670+242,400+3,287,263=49,839,760$ kilometers squared
e) We first order the areas from the largest to the smallest.
$=17,098,242;9,984,670;9,629,091;9,598,094;3,287,263;242,400$
Which correspond to the following countries
