Answer:
4.5611 m
Step-by-step explanation:
First we should find the area of the the total circle, which is 12.57, with a radius of 2 m. Next, we need to find the area of the square, which is 8.0089, given that both sides are 2.83 m. Finally, we subtract the square from the total, which is 12.57-8.0089 = 4.5611 m.
Hope this helps!
