A triangle is dilated by a scale factor of ⅓ to produce a new triangle. Which of the following best describes the relationship between the perimeter of the original triangle compared to the perimeter of the new triangle?

• The perimeter of the new triangle is ⅓ that of the original triangle
• The perimeter of the new triangle is 3 times that of the original triangle.
• The perimeter of the new triangle is 1/9 that of the original triangle.
• The perimeter of the new triangle is 9 times that of the original triangle
