Answer:
174 ft²
Step-by-step explanation:
The polygon cam be decomposed into two rectangles.
The area of the polygon = rectangle A + rectangle B
Area of rectangle A = L* W
L = 18 ft
W = 9 ft
Area of rectangle A = 18*9 = 162 ft²
Area of rectangle B = L* W
L = 20 - 18 = 2 ft
W = 6 ft
Area of rectangle A = 2*6 = 12 ft²
✔️Area of the polygon = 162 + 12 = 174 ft²
