Step-by-step explanation:

★ QUESTION :

Find the side of traingle are in the ratio 1 : 2 : 3. If the perimeter is 36 cm, Find its side.

★ CONCEPT USED :

Perimeter of triangle = Sum of all the sides of the triangle

★ SOLUTION :

Let the ratio of the sides of the triangle be x : 2x : 3x

According to the Question,

x + 2x + 3x = 36cm

→ 6x = 36cm

→ x = $\sf { \frac{36cm}{6} }$

→ x = 6cm

Therefore ,

x = 6cm

2x = 2 × 6cm = 12cm

3x = 3 × 6cm = 18cm

Therefore , the sides of the triangle are 6cm , 12cm and 18cm respectively.

★ ANSWER :

The sides of the triangle are 6cm , 12cm and 18cm respectively.
