Answer:

A

Step-by-step explanation:

Area of square WXYZ is 9. ABCD has 4 times larger area which means ABCD has area of 36. Area of a square is the side length squared. Square root of 9 is 3 so WXYZ has side length of 3. ABCD has side length of 6 by the same logic. The difference between 6 and 3 is 3 so the answer is A.
