12x9=108
108x8=864
Answer:
y=-x +4
Step-by-step explanation:
y-2= -1(x-2)
y-2=-x +2
y= -x +4
I think that the answer is .00004

Since there are 3 lines (triangle), perimeter is simply the sum of those sides
find each side using distance (d) formula:
![(d) = \sqrt{( {(x2 - x1)}^{2} + {(y2 - y1)}^{2} )}](https://tex.z-dn.net/?f=%28d%29%20%3D%20%20%5Csqrt%7B%28%20%7B%28x2%20-%20x1%29%7D%5E%7B2%7D%20%2B%20%20%7B%28y2%20-%20y1%29%7D%5E%7B2%7D%20%20%29%7D%20)
where two points of the line lie at (x1, y1) and (x2, y2)
let's name the points of our triangle to make it easier: A = (8, 2), B = (8, 6), C = (6, 6)
![d(ab) = \sqrt{( {(8 - 8)}^{2} + {(6 - 2)}^{2} )} \\ = \sqrt{ {4}^{2} } = 4](https://tex.z-dn.net/?f=d%28ab%29%20%3D%20%20%5Csqrt%7B%28%20%7B%288%20-%208%29%7D%5E%7B2%7D%20%2B%20%20%7B%286%20-%202%29%7D%5E%7B2%7D%20%20%29%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%20%7B4%7D%5E%7B2%7D%20%7D%20%20%3D%204)
![d(bc) = \sqrt{( {(6 - 8)}^{2} + {(6 - 6)}^{2})} \\ = \sqrt{{2}^{2} } = 2](https://tex.z-dn.net/?f=d%28bc%29%20%3D%20%20%5Csqrt%7B%28%20%7B%286%20-%208%29%7D%5E%7B2%7D%20%2B%20%20%7B%286%20-%206%29%7D%5E%7B2%7D%29%7D%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%7B2%7D%5E%7B2%7D%20%7D%20%20%3D%202)
![d(ac) = \sqrt{( {(6 - 8)}^{2} + {(6 - 2)}^{2} )} \\ = \sqrt{( {2}^{2} + {4}^{2}) } = \sqrt{(4 + 16)} \\ = \sqrt{20} = 2 \sqrt{5} = 4.47](https://tex.z-dn.net/?f=d%28ac%29%20%3D%20%20%5Csqrt%7B%28%20%7B%286%20-%208%29%7D%5E%7B2%7D%20%2B%20%20%7B%286%20-%202%29%7D%5E%7B2%7D%20%20%29%7D%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%28%20%7B2%7D%5E%7B2%7D%20%2B%20%20%7B4%7D%5E%7B2%7D%29%20%7D%20%20%3D%20%20%5Csqrt%7B%284%20%2B%2016%29%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B20%7D%20%20%3D%202%20%5Csqrt%7B5%7D%20%20%3D%204.47)
So now for P add AB + BC + AC = 4+2+4.47
P = 10.47 units squared
