Question

Question 15Kelsey measured an apartment and made a scale drawing.

Answer 1

According to the information given in the exercise, the length of the rug in real life is:

`l_r=5ft`

And the length of the rug in the scale drawing is the following:

`l_(sd)=3in`

Then, the scale factor in this case can be calculated as following:

`scale\text{ }factor=(l_r)/(l_(sd))`

As you can notice, you can divide the actual length (in this case the length of the rug in the real life) by the length of the rug in the scale drawing.

Therefore:

`\begin{gathered} scale\text{ }factor=(5ft)/(3ft) \\ \\ scale\text{ }factor=(3)/(5) \end{gathered}`

The answer is: Third option.
