This is for the table
X | 0, 1, 1, 4, 4
Y | 0,-1,1,-2,2
X | 10,10,10,10,10
Y | 0,2,4,6,8
The perimeter of the triangle is 13.56 units.
The perimeter of a shape on a coordinate plane is found by finding the distance between all points, and then adding them together. It's easier to write it out than to type so I'll attach a photo of my work.
