The scale factor is 3.

Step-by-step explanation:

Since,

∵ If sides of a polygon are changed by a scale factor 'a' then its perimeter is also changed by the same scale factor,

By the given drawing,

The actual perimeter of the polygon = 10 unit,

Also, the scaled perimeter = 30 units ( given )

Hence,
