# Sides of a triangle are in ratio 2 : 3 : 4. Its perimeter is 27 cm. Find the length of each side.

The perimeter of a triangle means the sum of its boundary or all three sides.

## Answer: The length of the sides of the triangle are 6 cm, 9 cm, and 12 cm.

Let's find the length of each side.

**Explanation:**

Given: The sides of the triangle are in the ratio 2: 3: 4

Perimeter of the triangle = 27cm

Let's consider these sides to be 2x, 3x and 4x

Perimeter of a triangle is the sum of all the three sides.

Therefore, 2x + 3x + 4x = 27 (since, perimeter is given as 27)

9x = 27

x = 3

Thus, by back substituting the value of x in 2x, 3x and 4x we get,

2x = 2 × 3 = 6

3x = 3 × 3 = 9

4x = 4 × 3 = 12

### Thus, the length of the sides of the triangle are 6 cm, 9 cm, and 12 cm.
