Question

What is the perimeter of a triangle with corners at `(3 ,5 )`, `(1 ,6 )`, and `(4 ,3 )`?

Answer 1

`P= sqrt(29)+sqrt(18)+sqrt(5)`

Explanation:

Use the distance formula using the verteces of a triangle:
`A(3,5), B(1,6)` and `C(4,3)`
`bar(AB)=sqrt((3-1)^2+(1-6)^2)` following the same strategy for
`bar(BC)` and `bar(CA)`
`P=sqrt((3-1)^2+(1-6)^2)+sqrt((1-4)^2+(6-3)^2)+sqrt((4-3)^2+(3-5)^2)`
`P= sqrt(29)+sqrt(18)+sqrt(5)`
