Question

What is the perimeter of a triangle with corners at `(1 ,4 )`, `(6 ,3 )`, and `(4 ,2 )`?

Answer 1

Perimeter = 10.995

Explanation:

Let a, b, c be the sides. Sum of the three sides will give the perimeter.

`a=sqrt((4-6)^2+(2-3)^2)=sqrt5=2.236`
`b=sqrt((4-1)^2+(2-4)^2)=sqrt13=3.606`
`c=sqrt((1-6)^2+(4-3)^2)=sqrt26=5.099`

Perimeter `=a+b+c=2.236+3.606+5.099=`10.995
