1) Find the length of the second side of the triangle.
Since we know that it is 5.9 cm shorter than the length of the first side, its value will be:
47.6 – 5.9 = 41.7 cm.
2) Determine the perimeter of the triangle.
The perimeter is the sum of all sides of the shape.
In this case, we get:
47.6 + 41.7 + 40.2 = 129.8 cm.
Answer: The perimeter of the triangle is 129.8 cm.
