12 x 6 I think ur answer would be...
it's C because the floor area is 120 square feet and the walls are 8 feet so if you multiply 120 × 8 you get 960.

Step-by-step explanation:
.3455 is the correct answer.
The distance formula is:
![d= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B%28x_1-x_2%29%5E2%2B%28y_1-y_2%29%5E2%7D%20)
We are given two points in the form (x,y), so plug in the values to the distance formula:
![d= \sqrt{(-10-15)^2-(12-12)^2}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B%28-10-15%29%5E2-%2812-12%29%5E2%7D%20)
Next we can simplify. We know that 12-12 is 0, so we can drop it from the equation, as it will not affect our answer. Also, we know that -10-15 is -25:
![d= \sqrt{(-25)^2}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B%28-25%29%5E2%7D%20)
The square and square root cancel each other out leaving us with 25.
The answer is 25.
