A triangle has side lengths of (7m-2) centimeters (9m-5) centimeters and (6n-1) centimeters which expression represents the perimeter in centimeters of the triangle
The perimeter of a triangle is the sum of the lengths of all three sides.
So, the perimeter of this triangle in centimeters is:
(7m-2) + (9m-5) + (6n-1) = 7m + 9m + 6n - 2 - 5 - 1 = 16m + 6n - 8 cm.
