Let the sides be
2x, 5x and 7x.....
Given,
shortest side = 6 cm.
But shortest side = 2x
Thus, 2x = 6
so, x is 3
Perimeter of ∆ = 2x + 5x + 7x
= 14x
= 14*3
= 42 cm.....
Feel free to ask any doubts

step by step explanation:
Here,the ratio of sides of triangle =2:5:7
,smallest side=6cm,
let the common multiple for given ratio be x,
therefore sides be 2x,5x,7x.
smallest side =2x=6
therefore x=6/2
x =3 ...(1)
perimeter of triangle = 2x+5x+7x
=14x
=14×3 ...(from(1))
=42cm
Ans ; perimeter of triangle is 42cm
