To calculate the area of the complex shape:
⇒ must separate the shape into simpler shape
Let's calculate:
[tex]Area = 9*6+9*6=54+54=108[/tex]
[tex]Area= 9*3=27[/tex]
[tex]Area = \frac{1}{2}* 3*5.4+\frac{1}{2}* 3*5.4=8.1+8.1=16.2[/tex]
Total Area = [tex]108+27+16.2= 151.2[/tex]
Answer: 151.2 ft²
Hope that helps!
