Answer:
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.
