Answer:
12 1/4 or 49/4
Step-by-step explanation:
1. Change the mixed numbers into improper fractions
3 1/2 x 3 1/2 to 7/2 x 7/2
2. Multiply the numerators with each other, and the denominators with each other and put back into a fraction
7x7=49 2x2=4 -> 49/4
3. Put the fraction back into a mixed number (optional)
49/4 = 12 1/4
