Question

the perimetre of a triangle is 18m and its sides are in ratio 1:2:3, find the sides of the triangle.​

Answer 1

Answer:

3 cm , 6 cm and 9 cm

Step-by-step explanation:

1:2:3

=> 1+2+3

=> 6

1/6 * 18 = 3 / 1

2/6 * 18 = 6 /1

3/6 * 18 = 9 / 1

Answer 2

Answer :

• First side 1x = 1 × 3 = 3m

• Second side 2x = 2 × 3 = 6m

• Third side 3x = 3 × 3 = 9m

Given :

• Perimeter of triangle = 18m

• Sides in ratio = 1:2:3.

To find :

• The sides of the triangle = ?

Step-by-step explanation :

Let the sides of traingle 1x,2x and 3x be.

Perimeter of the traingle = 18 m

•°• 18 = 1x + 2x + 3x

➟ 18 = 6x

➟ 18/6 = x

Or x = 18/6

➟ x = 3

So, the first side 1x = 1 × 3 = 3m

Second side 2x = 2 × 3 = 6m

Third side 3x = 3 × 3 = 9m
