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?
To find the scale factor, we will divide the length of the enlarged side by the length of the original side.
The original side measures 3 centimeters.
The enlarged side measures 8 centimeters.
Scale factor = Enlarged side / Original side
Scale factor = 8 cm / 3 cm = 8/3 ≈ 2.67
Therefore, Terry used a scale factor of approximately 2.67.
