96 inches = x feet
12/96 = 1/x

12x = 96
x = 96/12
x = 8
96 inches = 8 feet

Answers
The large square is 6 by 6 so it has area 6*6 = 36
The small square is 2 by 2 (since 6-2-2 = 2), so it has area 2*2 = 4
The difference in areas is 36 - 4 = 32 which is the area of the shaded region

In summary:
1. The unshaded square (smallest square) has area 4 square inches
2. The area of the large square is 36 square inches
3. The shaded region (area of the frame) has area 32 square inches
