Solution

For this case we have the following:

2 1/2 = 5/2 ft

1 3/4 = 7/4 ft

the ratio is 20/14 = 10/7

The new dimensions are: 11 and 9 inches

So then we can create the following equation:

11/x = 10/7

Solving for x we got:

x = 11*7/10 = 77/10

Then the scaled notebook should be with the following dimensions:

11 in and 7.7 in

Final answer

Scale factor= 10/7
