Definition: Scaled Drawing. A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount
Example
Example #1:
Suppose a problem tells you that the length of a vehicle is drawn to scale. The scale of the drawing is 1:20.
If the length of the drawing of the vehicle on paper is 12 inches, how long is the vehicle in real life?
Set up a proportion that will look like the formula above picture
A scale drawing proportion
Do a cross product by multiplying the numerator of one fraction by the denominator of the other fraction
We get :
Length of drawing × 20 = Real length × 1
Since length of drawing = 12, we get:
12 × 20 = Real length × 1
240 inches = Real length
The real length of the vehicle is 240 inches.
