Answer:
474.43 m²
Explanation:
The shape is composed of a rectangle and a parallelogram
Area of the composite shape = area of the rectangle + area of the parallelogram
= Length*Width + base*height
Where,
Length = 20.9 m
Width = 14.3 m
base = 20.9 m
height = 22.7 - 14.3 = 8.4 m
Area = 20.9*14.3 + 20.9*8.4
Area = 298.87 + 175.56
= 474.43 m²
