Question

Brooke paints the outsides of the square walls and triangular ceilings of her treehouse. What is the area?

Answer 1

The answer is "
`216\ ft^2`"

Explanation:

Please find the graph file in the attachment.

The area of its tree house's outsides of the square walls and triangular ceilings is equivalent to four squares with four triangles,

`\to A=4[(6)^2+(1)/(2) (6)(6)]\\\\`

`=4[36+(1)/(2) (36)]\\\\=4[36+18]\\\\=4[ 54]\\\\=216\ ft^2`
