To solve this problem you must apply the proccedure shown below:

1. You have that the following information given in the problem above: The photograph is reduced by a scale factor of 3/8 and the original had a length of 20 inches,

2 - Therefore you have:

length=20 inches - (20 inches x 3/8)

length=20 inches-7.5 inches

length=12.5 inches

3 - Then, as you can see, the answer is: 12.5 inches.
