Assuming pi is 3 (as stated on the paper) the area of the circle would be 75. The area of a circle is pi r^2, and since in this case pi is rounded to 3, and the radius is 5, it would be 3(5^2) = 325 = 75.
The area of the square would be 144. Area of a square is side side, which in this case is 12 * 12, which equals 144.
Then subtract the area of the circle from the square to get the final answer.
144 - 75 = 69
The final answer is 69 cm^2
