Question

A triangle has side lengths of (5.5x+6.2y) centimeters, (4.3x+8.3z) centimeters, and (1.6z - 5.1y) centimeters, what expression of the perimeter in centimeters of the triangle

Answer 1

9.8x + 1.1y + 9.9z

Explanation:

To get the perimeter of a triangle, we need to get the sum of the lengths of all the sides. This simply mean to arrive at the value for the perimeter of a triangle, we add the values of the length of the three sides together.

Hence, in this question, we simply add the values together as shown below:

The perimeter P of the triangle will be: 5.5x +6.2y + 4.3x + 8.3z + 1.6z - 5.1y = 9.8x + 1.1y + 9.9z
