Answer:
The perimeter of the triangle is 135 cm
Step-by-step explanation:
* Lets explain how to find the perimeter of a triangle
- The perimeter of any triangle is the sum of the lengths of its three sides
- The perimeter of the scalene triangle is P = S1 + S2 + S3
- The perimeter of the isosceles triangle is P = 2S + S1
- The perimeter of the equilateral triangle is P = 3S
* Lets solve the problem
∵ The length of the 1st side is 55 cm
∴ S1 = 55 cm
∵ The length of the 2nd side is 48 cm
∴ S2 = 48 cm
∵ The length of the 3rd side is 32 cm
∴ S3 = 32 cm
∵ The triangle is scalene
∴ P = S1 + S2 + S3
∴ P = 55 + 48 + 32 = 135 cm
* The perimeter of the triangle is 135 cm
