Question

the perimeter of a traingle is 72cm and its sides are in the ratio of 1:2:3: find its sides ​

Answer 1

Step-by-step explanation:

let the common variable be x

1x,2x,3x

1x+2x+3x=72

6x=72

x=12

Now,

put the value of x=12

1x=12

2x=24

3x=36

Answer 2

Step-by-step explanation:

perimeter of a triangle = 72 cm

sides are 1:2:3

sides a =1x

side b =2x

side c = 3x

perimeter of a triangle = 72 cm

1x+2x+3x = 72 cm

6x = 72cm

x = 72cm / 6

x = 12cm

Thanks you

sides a = 1x = 1×12cm = 12cm

side b = 2x = 2× 12cm = 24 cm

side c = 3x = 3×12 cm = 36cm
