Answer: the area of the shaded region is 72.96 ft²
Step-by-step explanation:
The formula for determining the area of a circle is expressed as 
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Diameter of circle = 16 feet
Radius = diameter/2 = 16/2 = 8 feet
Area of circle = 3.14 × 8² = 200.96ft²
The sides of the square are equal. To determine the length of each side of the square, L, we would apply Pythagoras theorem which is expressed as 
Hypotenuse² = opposite side² + adjacent side²
Therefore,
16² = L² + L² 
256 = 2L²
L² = 256/2 = 128
L = √128 ft
Area of the square is 
L² = (√128)²
Area = 128 ft²
Area of shaded region is 
200.96 - 128 = 72.96 ft²
