Terry designs a drawing of a pentagon. Each side of it measures 3 centimeters. He enlarges it so that each side is now 8 centimeters. What scale factor did he use?
2 and 2 over 3
or 2 and 1 over 3
He enlarged the drawing from 3 centimeters to 8 centimeters. To find the scale factor, you can divide the length of the enlarged side by the length of the original side:
8 centimeters / 3 centimeters = 2 and 2/3
Therefore, Terry used a scale factor of 2 and 2/3.
