of Russia?

Answer 1

1,750 islands

Explanation:

In order to determine how many islands the size of Jamaica it would take to equal the size of Russia in terms of land area, we can simply divide the area of Russia by the area of Jamaica:

`\textsf{Area of Russia = $7 × 10^6 $square miles}`

`\textsf{Area of Jamaica =$ 4 × 10^3 $square miles}`

The number of Jamaican-sized islands to equal the size of Russia:

`\sf \frac{\textsf{(Area of Russia) }}{\textsf{ (Area of Jamaica)}}`

`\sf \textsf{Number of islands} =( (7 × 10^6) )/((4 × 10^3))`

Now, let's simplify this:

`\sf \textsf{Number of islands} =(7)/(4)* 10^(6-3)`

`\sf \textsf{Number of islands} = 1.75* 1000=1750`

So, it would take approximately 1,750 islands the size of Jamaica to equal the land area of Russia.
