Answer 1

It determines the size of objects portrayed on a map by it being able to put things on the map where ever they want

Answer 2

Cartographers use mathematical formulas to transfer information from the three-dimensional globe to the two-dimensional map.

Step-by-step explanation:

Cartographers adapt the three-dimensional globe image onto a flat map by creating a scale map projection. In cartography, scale refers to the ratio between length or size of an area on a map and the actual length or size of that area on the surface of the Earth.
