Question

Leo designs a piece of jewelry in the shape of a regular pentagon. Each side of the object measures 3 centimeters. Leo photographs the object, enlarges it so that the sides each measure 8 centimeters, and prints the photo. What scale factor did Leo use to create the photograph from the original?

Answer 1

To find the scale factor, we need to divide the length of a side in the photograph by the length of a side in the original. The length of a side in the photograph is 8 centimeters, and the length of a side in the original is 3 centimeters. So the scale factor is $8/3=\boxed{\frac{8}{3}}$.
