Let x represent the length of the smallest side. If the lengths are consecutive integers, then the next side would be x + 1, and the one after that would be one greater, x + 1 + 1 = x + 2. All three sides add up to the perimeter of the triangle, 195.
(x) + (x+1) + (x+2) = 195
x + x + 1 + x + 2 = 195
3x + 3 = 195
3x = 192
x = 64
The shortest side is 64mm, and the other two sides are 65mm and 66mm.
