One side of the triangle is 4.5 cm, which is 3.3 cm less than the second side and 0.6 cm

One side of the triangle is 4.5 cm, which is 3.3 cm less than the second side and 0.6 cm more than the third. Find the perimeter of the triangle.

The first step is to calculate the length of the second side of the triangle:
1) 4.5 cm + 3.3 cm = 7.8 cm length of the second side of the triangle.
The second step is to calculate the length of the third side:
2) 4.5cm – 0.6cm = 3.9cm third side length.
The third step is to calculate the perimeter of the triangle by the formula the sum of the lengths of its sides:
3) 4.5 cm + 7.8 cm + 3.9 cm = 16.2 cm perimeter of the triangle.
Answer: The perimeter of the triangle is 16.2 cm.
