Question

Can somebody help me find the surface area

Answer 1

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

`Area = 9*6+9*6=54+54=108`

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

`Area= 9*3=27`

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

`Area = (1)/(2)* 3*5.4+(1)/(2)* 3*5.4=8.1+8.1=16.2`

Total Area =
`108+27+16.2= 151.2`

Answer: 151.2 ft²

Hope that helps!
