Question

can someone explain about map scales interms of areas and perimeters

Answer 1

Hi there
Basically drawings on the map are SIMILAR FIGURES to actual geometric features of the surface of the earth (we suppose that earth IS flat, and that locations from above look flat. As we all know one has to suppose that)
Now similar figures have a "ZOOM RATIO" - simply the ratio of their sizes.
Let Us say \[Z = \frac{size-picture}{size-original}\]

Answer 2

Now the Z is the scale of the map. BUUT the areas - being proportional to square of size!
Scale as Z^2 that is if the map is smaller by Z, the areas on the map are smaller by
\[Z^2\]
