Answer:
151.3 cm²
Explanation:
The shape is composed of a semicircle and a rectangle
Area of the shape = area of the semicircle + area of the rectangle
Area of the shape = ½(πr²) + L*W
r = ½(16 - 6) = ½(10) = 5 cm
L = 16 cm
W = 7 cm
Plug in the values
Area of the shape = ½(π*5²) + 16*7
Area = 39.27 + 112
Area = 151.3 cm² (nearest tenth)
