The answer is the first option, 28.6 m^2.
First, you know that the area of the square is 4 × 4 = 16 m^2.
The area of a regular circle is π × radius^2, but for a quarter circle, that changes to (π × radius^2)/4. We use 3.14 as π, and 4 is the radius, so we get (3.14 × 4^2)/4 = 50.24/4 = 12.56. Now we just need to add this to our original 16 m^2 to get the answer of 28.56, which rounds to 28.6 m^2. I hope this helps!
