Question

List the components in the proportion relationship used to find missing value in scale drawing?

Answer 1

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:

$Height=1.5(1/10)=0.15m \\ \\ Length=2(1/10)=0.2m$

So the components are:

• Measurements of the original object
• Measurements of the drawing
• Scale factor
