Answer:

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
