**Given:**

The side of a triangle are in the ratio of 3 ∶ 4 ∶ 5

The length of the longest side is 170 mm

**Calculations:**

Let the length of the longest side be 5x

⇒ 5x = 170

⇒ x = 34

Length of the first side = 3x = 3 × 34 = 102 mm

Length of the second side = 4x = 4 × 34 = 136 mm

**∴ The Lengths of the other two sides are 102 mm and 136 mm**
