Answer:
144 - 36pi
Step-by-step explanation:
1) Since the side lengths of the square are 12 units, the midpoints divide each side into two 6 unit lengths.
2) Those 6 unit lengths are radii of a quarter of a circle.
3) We can use the equation pi × r^2 to calculate the area of the four quarter circles.
4) pi × 6^2
5) 36pi
6) The area of the original square is 12 × 12, which is 144.
7) 144 - 36pi is your answer.
