Answer:
55.04 ft²
Step-by-step explanation:
Calculate the area of the square, the area of the circle, then subtract the area of the circle from the area of the square.
Area of square = 16 x 16 = 256 ft²
Area of circle = r²
radius = 16 ÷ 2 = 8
⇒ Area of circle = 3.14 x 8² = 200.96 ft²
Shaded area = 256 - 200.96 = 55.04 ft²
