Area of the composite figure = 390 ft²
Solution:
The composite figure is splitted into two rectangles.
The image is attached below.
Length of vertical rectangle = 20 ft
Width of vertical rectangle = 7 ft
Area of vertical rectangle = length × width
= 20 × 7
Area of vertical rectangle = 140 ft²
Length of top rectangle = 25 ft
Width of top rectangle = 30 - 20 = 10 ft
Area of top rectangle = length × width
= 25 × 10
Area of top rectangle = 250 ft²
Area of the composite figure = 140 ft² + 250 ft²
Area of the composite figure = 390 ft²
