Coplanar points are 3 or more points which lie in the same plane, so any set of 3 points is coplanar
The perimeter is 6x + 12, and a model example is attached.
All three sides of an equilateral triangle are the same, so multiply the side length by 3 to find the perimeter.
3(2x + 4)
Now distribute the 3.
3 * 2x + 3 * 4
6x + 12
