Answer:
First, find the perimeter of each square. The sides of a square are always congruent; so, to find the perimeter multiply the side length by 4, the number of sides. This means the perimeter of the first square is 12 and the second one is 24. So, the perimeter is twice as large (12 units larger). This is because the factors also have the same relationship. 6 is twice as large as 3. Therefore, the perimeter must also be twice as large.
