Question

The question is “what is the scale factor”? I just need a brief explanation with the answer

Answer 1

The scale factor is usually calculated with:

`=\frac{\text{image length}}{object\text{ length}}`

From the question, the dimension with the dotted line is the image, while the dimension with the bold line is the object.

So the scale factor therefore is:

`\begin{gathered} =(1in)/(2in) \\ =(1)/(2) \end{gathered}`
