Answer:
21.5%
Step-by-step explanation:
The first step is to find the area of the square, and then the area of the circles inside. The area of the square is the side length squared, or in this case 2304. Since the circles are inscribed in the square, they are touching the borders, and two of them perfectly cross to the other side. Therefore, the diameter of one of the circles is half of the side length of the square, and the radius is a quarter. Thus, the area of one of the circles is 
, which when multiplied by the 4 circles yields about 1809.557. Subtracting this from the total area of the square, you get 494.443, which when divided by the total area of the square gives approximately 21.5%. Hope this helps!
