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?

Answer 1

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.
