Question

Find the perimeter of a triangle with the verticies at (0,2), (-2,-2) and (2,-2)

Answer 1

I got 4 sqrt 5 plus 4 sqrt 2

=14.6 approximately

Explanation:

We know that perimeter means area around, right? So, must add up the distances between each of this points. What I would use is the distance formula. It might also help to graph the points on a coordinate plane :)
