A rectangle has a perimeter of 30. It is dilated by a scale factor of 2.

What is the new perimeter?

It is 60.

Step-by-step explanation:

When shapes are dilated (when they get bigger or smaller), perimeter changes linearly-in direct proportion with length. This means if the scale factor is 2, then you multiply it by 2. 2 multiplied by 30 equals 60.
