Question

the perimeter of a triangle is 72 cm and its side the ratio of 1:2:3 find its side ​

Answer 1

Answer:

Let the sides be =1x, 2x, 3x.

So,

Perimeter=sum of sides

= 6x= 72cm

=x= 12cm

So,sides =

1x= 12cm

2x= 24cm

3x= 36cm

Answer 2

Answer:

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

As we know,

$perimeter = a + b + c$

x+2x+3x=72cm

6x=72cm

x=72cm/6

x=12cm

Therefore,3 sides are

1x=12cm

2x=24cm

3x=36cm
