First, find the area of the whole square.
Area= Base times height= 48 times 96 = 4608
Next, find the area of ONE circle. The diameter is 12, so the radius would be 6
A=πr sqaured= 3.14 times 6 squared = 113.04
Next multiply by 3, since there are 3 circles.
113.04 times 3 =339.12
Subtract this value from the total area (4608)
4608-339.12=4268.88
ANSWER: 4268.88
