Answer:
163.47
Explanation:
We know the area of the whole rectangle by multiplying 12 by 22 to get 264. Now we just have to find the area of the circles and subtract it from the rectangle.
The area of a circle is πr^2. These circles' radii is 4, so 4^2π = 16π
Since there are 2 circles, double 16π to get 32π, 32π is equal to 100.53096491, rounded to 100.531. 264 - 100.531 = 163.469, rounded to 163.47
