Answer:

_________

Given :

° SIDES of a triangle in RATIO.

let , all ratio number be x , i.e., 1x , 2x & 3x .

° Perimeter of triangle = 30cm

To FIND sides :

Solution :

• As we know , perimeter of a triangle = sum of all sides

= 1x + 2x + 3x = 30cm

= 6x = 30cm

= x = 5cm

* Thus , 1x = 1 × 5cm = 5cm

2x = 2 × 5cm = 10cm

3x = 3 × 5cm = 15

~ Hence , the sides of a triangle is 5cm , 10cm and 15cm , respectively .
