1. Guess the factor by which the area of the first country must be multiplied
to get the area of the second country. 2. The arrows help you:
An upward arrow means the correct answer is higher than the number you entered.
A downward arrow means the correct answer is lower than the number you entered. 3. Your answer counts as correct if the factor you enter is within 2% of the correct factor. 4. The world map (Google Maps) will help you.
Warning: Google Maps uses the Mercator projection, so the areas around the North and South Poles
are shown larger than they actually are. 5. Example A:
South Korea 100,210 km²
Poland 312,679 km²
The correct factor is 3.120
South Korea × 3.120 = Poland 6. Example B:
South Korea 100,210 km²
Ireland 70,273 km²
The correct factor is 0.701
South Korea × 0.701 = Ireland 7. You have six attempts available.
