A scale factor of 2 would be the perfect scale for the scale drawing.
We are given original dimensions of tech fingerboard as;
Length = 100 mm
Width = 25 mm
Now, from conversions we know that;
1 inch = 25.4 mm
Since Giovanni wants to make a larger scale drawing on an 8 1/2 inch by 11-inch piece of paper, then we can say that;
11-inch = 25.4 * 11 = 279.4 mm
8 1/2 inch = 8 1/2 * 25.4 = 215.9 mm
Thus;
New Length/old length = 279.4/100 = 2.794
Since that is the maximum scale for the drawing paper, then we can say that something lesser like a scale factor of 2 would be the perfect scale for the scale drawing.
