Answer :

Using proportions, it is found that the garage is 14 millimeters wide in the drawing.

What is a proportion?

  • A proportion is a fraction of total amount, and the measures are related using a rule of three.
  • In this problem, the scale states that a drawing of 7 millimeters represent a real dimension of 4 meters. Considering the garage is 8 meters wide in real life, what will be the dimension of the drawing?

The rule of three is:

7 millimeters - 4 meters

x millimeters - 8 meters

Applying cross multiplication:

[tex]4x = 7(8)[/tex]

[tex]x = \frac{56}{4}[/tex]
