Find the perimeter of triangle ABC.
Harlamova29_29 [7]
By definition, the perimeter of the triangle is the sum of its sides.
 We must then use the formula of distance between points:
 d =  \sqrt{(x2-x1) ^ 2 + (y2-y1) ^ 2}
 We now look for the longitus for each of the sides:
 
 For L1:
 L1 = \sqrt{(6-2)^2 + (6-2)^2}
 L1 =  \sqrt{32} &#10;
 L1 = 4\sqrt{2}

 For L2:
 L2 = \sqrt{(7-2)^2 + (-3-2)^2}
 L2 = \sqrt{50}
 L2 = 5\sqrt{2}

 For L3:
 L3 = \sqrt{(7-6)^2 + (-3-6)^2}
 L3 = \sqrt{82}
 
 Then, the perimeter is given by:
 P = L1 + L2 + L3
 Substituting values we have:
 P = 4\sqrt{2} + 5\sqrt{2} + \sqrt{82} &#10;&#10;P = 9\sqrt{2} + \sqrt{82}

 Answer:
 
the perimeter of triangle ABC is:
 
none of the above.
