Answer:

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

Step-by-step 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,

$\to A=4[(6)^2+\frac{1}{2} (6)(6)]\\\\$

$=4[36+\frac{1}{2} (36)]\\\\=4[36+18]\\\\=4[ 54]\\\\=216\ ft^2$

======================================================

Explanation:

Draw an xy grid and plot the point (-4,3) on it. Draw a segment from the origin to this point. Then draw a vertical line until reaching the x axis. See the diagram below.

We have a right triangle with legs of 4 and 3. The hypotenuse is $\sqrt{4^2+3^2} = \sqrt{16+9} = \sqrt{25} = 5$ through use of the pythagorean theorem.
