Answer 1

let the sides be x,2x and 3x
perimeter= a +b+c
30=x+2x+3x
30 = 6x
30/6 = x
x=5
therefore the smallest side =5 cm
I hope this will help u
Mark me as brainiest

Answer 2

Answer:

Step-by-step explanation:

Given ratio 1:3:2

=>1x:3x:2x=1:3:2,

Side1=1x

Side2=3x

Side3=2x

Perimeter=side1+side2+side3

Given perimeter=30

=>30=1x+3x+2x

30=6x

X=5

Side1 =5. Side2=15. Side3=10

Side 1 smallest
