Leo designs a piece of jewelry in the shape of a regular pentagon. Each side of the object measure 4 centimeters. Leo photographs the object, enlarges it so that the sides each measure 11 centimeters, and prints the photo. What scale factor did Leo use to create the photograph from the original?

1 answer

To find the scale factor, we can divide the length of the enlarged side by the length of the original side.

The length of the enlarged side is 11 centimeters.

The length of the original side is 4 centimeters.

So the scale factor is 11 centimeters / 4 centimeters = <<11/4=2.75>>2.75.

Therefore, Leo used a scale factor of 2.75 to create the photograph from the original.
