Answer:
27 cm squared
Explanation:
r = half of the diameter = 8 cm
area of circle = pi(r)^2 = 3.14 x (8 cm)^2 = 200.96 cm squared
area of rectangle = 16 cm x 8 cm = 128 cm squared
area of shaded region = area of the rectangle - (half of the area of the circle)
half of the area of the circle = 100.48 cm squared
therefore, area of shaded region = 128 cm squared - 100.48 cm squared
= 27.52 cm squared
