Question

The sides of a triangle are in ratio 1 : 2 : 3. If the perimeter of the triangle is 12 cm. The sides of the triangle are


​

Answer 1

Answer:

2 cm, 4 cm, 6cm.

Step-by-step explanation:

Let the ratio be x : 2x : 3x.

According to Question,

x + 2x + 3x = 12

=> 6x = 12

=> x = 12/6

=> x = 2

Hence, the sides are 2 cm, 4 cm and 6 cm.

Answer 2

Answer:

2,4,6

Step-by-step explanation:

perimeter (given) = 12

perimeter=sum of all sides

(let sum of all side be x)

12=1x+2x+3x

12=6x

so, X=2 cm

therefore the sides

1x= 1×2=2

2x=2×2=4

3x=3×2=6

therefore the sides of triangle are 2cm,4cm&6cm
