Answer:
No. It is not a reasonable scale
Step-by-step explanation:
The scale drawing must fit Sarah's paper. If it doesn't then the scale Sarah is using is not reasonable.
Now, we are told that the painting is 48 in x 120 in.
We are also told that on the scale 1in = 4 in.
Therefore, 48 in on the scale are
48 / 4 = 12 in
and 120 in on the scale are
120 / 4 = 30 in
This tells us that if Sarah chooses 1in = 4in as a scale, then her scaled painting would be 12 in x 30 in. Since Sarah's paper measures 12 in x 24 in ( which is smaller than 2 in x 30 in), her scaled painting would not fit into the paper.
Therefore, we conclude that Sarah's scale is not reasonable.
