One side of the triangle is 42 cm, which is 2.4 cm shorter than the length of the other side.

One side of the triangle is 42 cm, which is 2.4 cm shorter than the length of the other side. The third party is 35% of the amount of the first and second. Find the perimeter of the triangle.

To find the perimeter of a triangle, you need to find the lengths of each side P = a + b + c:

1) 42 + 2.4 = 44.4 centimeters length of the second side,

2) 44.4 + 42 = 86.4 centimeters the sum of the lengths of the first and second sides,

3) 35%: 100% = 0.35 expressed as a decimal percentage,

4) 0.35 * 86.4 = 30.24 centimeters third side length,

5) 42 + 44.4 + 30.24 = 86.4 + 30.24 = 116.64 centimeters perimeter of the triangle.

Answer: The perimeter of the triangle is 116.64 centimeters.
