The size of Florida on a map is determined by the scale of that map. A smaller scale number means that the map shows a smaller area in a larger size. Therefore, to determine which map will show Florida as the largest, we should look for the map with the smallest scale number.
Here are the scales given in the options:
- 500 km : 1 cm
- 1000 km : 1 cm
- 100 km : 1 cm
- 150 km : 1 cm
The smallest scale among these is 100 km : 1 cm. This means that 100 kilometers in reality is represented as 1 centimeter on the map, making it the most zoomed in, and therefore, Florida will appear the largest on this map.
So, the answer is:
a map with a scale of 100 km : 1 cm.
