What is the perimeter of a triangle with corners at #(9 ,2 )#, #(2 ,3 )#, and #(4 ,1 )#?
We know the distance between two points P(x1,y1) and Q(x2,y2) is given by PQ=
First we have to calculate the distance between (9,2)(2,3) ; (2,3)(4,1) and (4,1)(9,2) to get the lengths of the sides of triangles.
Hence lengths will be
Now the perimeter of the triangle is
