Answer 1

Step-by-step explanation:

Let sides be 2x,3x,4x

ATQ

$\qquad\qquad\bf{:}\longmapsto 2x=6$

$\qquad\qquad\bf{:}\longmapsto x=3$

$\qquad\qquad\bf{:}\longmapsto 3x=9$

$\qquad\qquad\bf{:}\longmapsto 4x=12$

Perimeter:-

$\qquad\qquad\bf{:}\longmapsto 6+9+12=27cm$

Answer 2

Answer:

24 cm

Step-by-step explanation:

ratio of sides is 2:3:4

2x=6

x=3

3x=9

4x=12

perimeter of ∆ = a+b+c

24cm
