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?

Question

2 1/3

2 2/3

3/8

Answer 1

To find the scale factor, we need to compare the lengths of the sides before and after the enlargement.

The original pentagon has side length 3 centimeters, and the enlarged photo has side length 8 centimeters.

Therefore, the scale factor is 8 centimeters / 3 centimeters = 8/3 = 2 2/3.

So the correct answer is 2 2/3.
