Answer: The new square has a sidelenght of 6 units.
Step-by-step explanation: Originally we have a square of a side length of 3 units, "dilating" it means that we make it bigger, and the factor means how many times.
So if the side length originally was 3 units, after dilating it with a scale factor of 2, the new side length will be:
2*3 = 6 units.
The new square has a side length of 6 units.
