Question

What is the perimeter of a triangle with corners at `(3 ,4 )`, `(2 ,0 )`, and `(4 ,5 )`?

Answer 1

Perimeter: `10.92` (approx.)

Explanation:

#{: ("Vertex Endpoints:",color(white)("X"),"Length of Side"), ((3,4):(2,0),,sqrt((3-2)^2+(4-0)^2)=sqrt(17)), ((2,0):(4,5),,sqrt((2-4)^2+(0-5)^2)=sqrt(29)), ((4,5):(3,4),,sqrt((4-3)^2+(5-4)^2)=sqrt(2)) :}#

Perimeter`= sqrt(17)+sqrt(29)+sqrt(2)`

(using a calculator)
`color(white)("XXXXX")~~10.92`
