Question

The sides of a triangle are in the ratio 3:2:4. If the perimeter of the triangle is 27cm, find the lemgth of each side.

Answer 1

Answer:

9 cm, 6 cm, and 12 cm.

Step-by-step explanation:

let the sides of triangle be 3x, 2x and 4x.

Perimeter of triangle = sum of all sides

=> 3x + 2x + 4x = 27

9x = 27

x = 3 cm

Now the length of sides are:

3x = 3 * 3 = 9 cm  

2x = 2 * 3 = 6 cm

4x = 4 * 3 = 12 cm

Answer 2

Step-by-step explanation:

et the sides of triangle be 3x, 2x and 4x.

Perimeter of triangle = sum of all sides

=> 3x + 2x + 4x = 27

9x = 27

x = 3 cm

Now the length of sides are:

3x = 3 * 3 = 9 cm  

2x = 2 * 3 = 6 cm

4x = 4 * 3 = 12 cm
