Answer:
a) The scale factor is 5
b) The scale factor is 4
Step-by-step explanation:
a) Measurement of the sheet is 8 1/2 in. by 11 in.
If we leave 1 in. margin on all 4 sides, then the picture will fit in the area of
6 1/2 in. by 9 in.
The original measurement of the painting is 30 in. by 22.5 in.
So, choosing a scale of 5 will be good because choosing scale 4 will exceed the width of the paper.
b) If we turn the paper on its side, then the width and height will be 9 in. by 6 1/2 in.
For this measurement, choosing a scale 4 would be fine because choosing scale 3 will exceed the width of the paper.
