Answer:
1800 square feet
Explanation:
Area of composite figure
Figure 1:
 length = 27 ft
Width = 24 ft
Area of figure1 = length * width
 = 27 * 24 
 = 648 square feet
Area of figure II:
 length = 27 ft
 Widht = 32 ft
Area of figure II = 27 *32
 = 864 square feet
Area of figure III:
 base = 18 ft
 height = 32 ft
 
 

Area of composit figure = 648 + 864 + 288
 = 1800 square feet
