The original photo has a perimeter of 24 cm. After dilation, the new perimeter is 60 cm.
The scale factor of the dilation can be found by dividing the new perimeter by the original perimeter:
scale factor = new perimeter / original perimeter = 60 cm / 24 cm = 2.5
Therefore, the scale factor of the dilation is 2.5.
Answer: 2.5
