And the length of car in her sketch is 8 inches.
<em>So, the ratio of the scale used by Tiffany as given is 2 inches : 12 feet.</em>
Now, to get the actual length of car by using cross multiplication method:

⇒ 
<em>By cross multiplying we get:</em>
⇒ 
<em>Dividing both sides by 2 we get:</em>
⇒ 
⇒ 
Therefore, the actual length of car is 48 feet.
