Question

The perimeter of a triangle is 36cm. if the sides are in the ratio 1:2:3 ratio, then find its all side

Answer 1

Heya !!!


Ratio of the sides of triangle are 1:2:3.


Let X be common multiple to these ratio of the sides then the sides becomes,

X , 2X and 3X.


Perimeter of triangle = 36


X + 2X + 3X = 36



6X = 36

X = 36/6 = 6


Therefore,



First Sides = X = 6 units


Second Side = 2X = 2 × 6 = 12 units.


And,



Third side = 3X = 3 × 6 = 18 units.

Answer 2

Let the sides be:
x , 2x , 3x respectively

Perimeter of a triangle = side+side+side

Perimeter = x + 2x + 3x
36 = 6x
x = 36/6
x = 6

Put the value of x in the sides that we have let above..

●x = 6
●2x = 2(6)
=12
●3x = 3(6)
=18

So clearly these sides are 6,12 and 18 cm
