Question 1118649
Just those points as a triangle?  Use the Distance Formula for the three sides.  Find the sum.


{{{sqrt((1-0)^2+(6-4)^2)+sqrt((0-3)^2+(4-2)^2)+sqrt((3-1)^2+(2-6)^2)}}}

{{{sqrt(5)+sqrt(13)+sqrt(4+4^2)}}}

{{{sqrt(5)+sqrt(13)+sqrt(20)}}}

{{{sqrt(5)+sqrt(13)+2*sqrt(5)}}}

{{{3*sqrt(5)+sqrt(13)}}}
