Explanation:
When we have relationships between two variables and their ratios are equivalent, we call this as proportional relationship. A scale drawing is a model that has been reduced or enlarged from its original size. Suppose you have a horse that measures 1,5m high by 2m long and want to draw a reduced model by a scale factor of 1:10, then your drawing will measure:
[tex]Height=1.5(1/10)=0.15m \\ \\ Length=2(1/10)=0.2m[/tex]
So the components are:
- Measurements of the original object
- Measurements of the drawing
- Scale factor
