<prompt> A1,1, B5,6 na C9,2Kuamua mzunguko wa pembe ABC ambapo A ni katika 1,1, B katika 5,6 na C katika 9,2.  <response>: To find the perimeter of triangle ABC, we need to find the length of each side and add them up. The length of a side can be found using the distance formula: the distance between two points x1, y1 and x2, y2 is given by the square root of x2-x12 y2-y12.Using this formula, we can find the lengths of the three sides of triangle ABC:AB 5-12 6-12 16 25 41BC 9-52 2-62 16 16 32CA 9-12 2-12 64 1 65Therefore, the perimeter of triangle ABC is AB BC CA 41 32 65 22.34.
