Final answer:
The perimeter of a triangle with sides of lengths x cm, y cm, and z cm is calculated by adding up the lengths of all its sides. Therefore, the perimeter P = x + y + z.
Step-by-step explanation:
The question is asking for the perimeter of a triangle. In mathematics, the perimeter of a shape is defined as the distance around its boundary. In the case of a triangle, the method of finding the perimeter is quite straight forward. You simply add up the lengths of all its sides. Hence for a triangle with sides of lengths x cm, y cm, and z cm, the perimeter P is given by the formula:
P = x + y + z
