Answer 1

You must use the distance formula for each of the coordinate points!

Answer 2

Ive already done that everytime I do it I get the wrong answer

Answer 3

You added up the 3 distances you got correct?

Answer 4

AB=√(-7-(-11)^2+(7-4)^2=(-18)^2+(3)^2=√324+9+√333=3√37
BC=√(-3-(-7))^2+(4-7)^2=(4)^2+(3)^2=√16+9=√25=5
CA=(-3-(-7))^2+(4-7)^2=(4)^2+(3)^2=√16+9=√25=5

AB+BC+CA=20.5
