So in this problem, we have been given three coordinates, that is minus 9, 3, 13, minus 1 and minus 3, minus 1.
00:07
Let it be a, b, c, which represents the triangle a, b, c.
00:12
We have to find the perimeter of the triangle, okay.
00:15
So let us find a b, b, c, then a c.
00:17
So we'll add them up and the sum will get us the perimeter.
00:21
Okay, so find, find, let us first find a, b.
00:25
So that is a formula for finding length of x, y.
00:28
Suppose we have to find the length of x, we have to, how we have to, how we have to, to calculate it it will nothing but so that exponent is x1 y1 and y coordinate is x2 y2 so the distance between them is nothing but x2 minus x1 whole square plus y2 minus y1 whole square so applying the same logic here the distance between ab will be minus 9 minus of minus whole 3 square plus 3 minus of minus 9 whole square but will become minus 6 plus whole square plus 12 square root over that is 36 plus 144 that is 1r088 188 that is 6 root 5.
01:03
Similarly we can find the value of bc.
01:05
So bc will be nothing but, see here, so bc will be nothing but 13 minus of minus 9 whole square plus minus 1 minus 3 whole square...
