To calculate the area of the complex shape:

 ⇒ must separate the shape into simpler shape

  • 2 rectangles with a length 9ft and a width 6ft
  • 1 rectangle with a length of 9 ft and a width 3ft
  • 2 triangles with a base of 3 ft and a height 5.4ft

Let's calculate:

  • 2 rectangles with a length 9ft and a width 6ft

            [tex]Area = 9*6+9*6=54+54=108[/tex]

  • 1 rectangle with a length of 9 ft and a width 3ft

             [tex]Area= 9*3=27[/tex]

  • 2 triangles with a base of 3 ft and a height 5.4ft

             [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
