The perimeter of the triangle is: (9.5n - 11.6p - 3.5q) cm.

<h3>What is the Perimeter of a Triangle?</h3>

The total length of all the sides of a triangle is equal to the perimeter of the triangle.

Given a triangle has the following lengths:

  • (2.9n-7.8p) centimeters,
  • (6.6n-6.4q) centimeters,
  • (2.9q-3.8p) centimeters.

The perimeter of the triangle = (2.9n-7.8p) + (6.6n-6.4q) + (2.9q-3.8p)

The perimeter of the triangle = 2.9n - 7.8p + 6.6n - 6.4q + 2.9q - 3.8p

Combine like terms together

The perimeter of the triangle = 2.9n + 6.6n - 7.8p - 3.8p - 6.4q + 2.9q

The perimeter of the triangle = 9.5n - 11.6p - 3.5q

Thus, the perimeter of the triangle is: (9.5n - 11.6p - 3.5q) cm.
