Answer:

  • 20x + 6.5

Step-by-step explanation:

The perimeter of a triangle represents the sum of all sides.

  • => Perimeter = (8x + 1.5) + (11x) + (x + 5)

Removing the brackets:

  • => (8x + 1.5) + (11x) + (x + 5)
  • => 8x + 1.5 + 11x + x + 5

Addling like terms:

  • => (8x + 11x + x) + (1.5 + 5)
  • => 20x + 6.5

Hence, 20x + 6.5 is the perimeter of the triangle.
