find the perimeter of a triangle whose vertices are the followinf specified points in the plane?

(9,-1)(-9,7)and(4,3)

• math -

The sides have lengths

√(18^2 + 8^2) = √388
√(5^2 + 4^2) = √41
√(13^2 + 4^2) = √185

Not much can be done to simplify that, so just add them up. The total is approx. 39.7
