Answer:
188.53 m²
Step-by-step explanation:
Total area of the stage = area of the rectangle + area of the semicircle
Area of rectangle = Length * Width
Length = 16 m
Width = 5.5 m
Area of rectangle = 16*5.5 = 88 m²
Area of semicircle = ½(πr²)
r = ½(16) = 8 m
Area = ½(π*8²)
Area = 100.53 m²
Total area of the stage = 88 + 100.53 = 188.53 m²
