Answer: 6 1/6
Step-by-step explanation:
1) First divide 10 1/2 = 5 1/4.
2) Then, since we divide 10 1/2 then we need to divide 12 1/3.
3) 12 1/3 divided by 2 = 6 1/6.
And there is your answer; 6 1/6
Find area of square: 7^2 = 49
Find radius of circle: 7/2=3.5

Remove area of circle from area of square:
49-38.465=10.535 cm^2
Answer A is the correct one :)
