Answer:

The scale factor is 4.

Step-by-step explanation:

Given,

The scale drawing has a scale of 3 inches : 1 feet,

That is, for 3 inches the measurement is 1 feet

We know that,

1 feet = 12 inches,

⇒ For 3 inches the measurement is 12 inches,

Thus, the scale factor = \frac{\text{Final measurement}}{\text{Initial measurement}}

=\frac{12}{3}

=4

Hence, the scale factor is 4.
