Answer:
25.9666 m
Step-by-step explanation:
The 4 arches combine to for a circle, so then you can find the area of the shaded region by subtracting the area of the square from the area of the circle.
The formula for area of a circle is A=[tex]\pi[/tex]r^2
Since the radius of the circle would be 11/2 or 5.5, the area if the circle would be [tex]\pi[/tex] x 5.5^2. This equals 95.0334.
The area of the square would be 11 x 11 = 121.
The 121-95.0334= 25.9666 m
