Question

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

Answer 1

Let x be the common ratio
Hence sides are
x
2x
3x



NOW PERIMETER IS 36
Hence
x+2x+3x=36
x=6


Hence sides are

x=6
2x=12
3x=18

Answer 2

Answer:

0

Step-by-step explanation:

let the sides be x, 2x,3x

perimeter = 30cm

l+b+h=30cm

x+2x+3x= 30cm

6x= 30cm

x= 30/6

x= 5

2x=10

3x=15

area of triangle by heron's formulae

$\sqrt 15(15-5)(15-10)(15-15)\\\sqrt 15*10*5*0\\0$
