Question

5. The sides of a triangle are in the ratio 1: 2: 3. If the perimeter is 36 cm, find its sides.​

Answer 1

Answer:

perimeter of triangle =sum of all side

therefore,

1x+2x+3x=36cm

6x=36cm

x=36cm/6

x=6cm

1st side=1×6=6cm

2nd side=2x=2×6=12cm

3rd side =3x=3×6=18cm

HOPE THIS HELPS!

Answer 2

Answer:

let the sides of triangle be 1x,2x,3x

1x+2x+3x=6x

6x=36cm

x=6cm

the sides are 6cm ,12cm,18cm
