How can I translate the size of a go kart track that i drew & scanned to my laptop into actual yards & inches?

Answer 1

use scales, in your case you just multiply it to a bigger number

if for example, your drawing is 10 inches but you actually want a 100 inches length you just say 1:10 (in words in goes like - one is to ten)

this is just simply enlarging it 10 times

Answer 2

I would first decide what is the smallest plot of land this could be used on. Then reference it according to that, and this will allow for adjustments to easily be made for larger plots.
if a one mile squar plot is required as the minimum, it is 5280 feet ( I think), and if your track is 2000 feet then you require 2000/5280 = 2/5.28.
now if someone comes along with a piece of land that is larger, say two miles they can multiply and reduce to adjust the size of the track to this size. This will tell you how large the track will be, based on the size of land you have.

Answer 3

find the size and scale of the drawing and convert...say the drawing is 3 in long, and the scale is 1:10
the actual size would be 3*10=30 in
