One side of the triangle is 42 cm 2 side is 3 times less than 1 and 3 is 32 cm more than the second

One side of the triangle is 42 cm 2 side is 3 times less than 1 and 3 is 32 cm more than the second, the perimeter of the triangle is calculated.

1) Since the second side of the triangle is 3 times smaller than the first side, then we calculate its value: 42: 3 = 14 (cm);

2) Knowing that the third side of the triangle is 32 cm larger than the second side, we find the value of the third side: 14 + 32 = 46 (cm);

3) Knowing the magnitudes of all sides of the triangle, we calculate the perimeter of the triangle using the formula: P = a + b + c = 42 + 14 + 46 = 102 (cm).

Answer: the perimeter of the triangle is 102 cm.
