Answer:
20.6
Step-by-step explanation:
Since the diameter of each circle is 4, the dimensions of the rectangle is 8x12
The area of the whole rectangle is 96
Now we need to find the area of the circles
The area of 1 circle is ...
So the area of all 6 circles is 12.56*6= 75.39...
So to find the area of yellow you have to subract the area of circle from the overall area of the rectangle
96-75.4=20.6
