Answer:
166 m^2
Step-by-step explanation:
Break the diagram into 3 rectangles:
rectangle 1 has 5 m width and 9 m length
rectangle 2 has 19 m width and 4 m length
rectangle 3 has 5 m width and 9 m length
area of rectangle 1 = l * w = 9m * 5m = 45 m^2
area of rectangle 2 = l * w = 4m * 19m = 76 m^2
area of rectangle 3 = l * w = 9m * 5m = 45 m^2
total area = area of rectangle 1 + area of rectangle 2 + area of rectangle 3
= 45m^2 + 76 m^2 + 45 m^2
= 166m^2
