Question 580305: what is the perimeter of a triangle in millimeters
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
Given three sides x, y, and z of a triangle, the perimeter is simply the sum of all three sides. So the perimeter is

P = x+y+z

For example, if the three sides of a triangle are 3, 4, and 5 mm, then x = 3, y = 4, and z = 5. We can then use this to find the perimeter.

P = x+y+z

P = 3+4+5

P = 12

So if the three sides of a triangle are 3, 4, and 5 mm, then the perimeter is 12 mm.
