equal sides are 4x-2 , 3x+1
4x-2 = 3x +1
4x- 3x = 1+2
x=3
sides are 4×3-2=10
3×3+1 =10
2×3-1=5
perimeter= 10+10+5 cm
=25cm
4x-2 = 3x +1
4x- 3x = 1+2
x=3
sides are 4×3-2=10
3×3+1 =10
2×3-1=5
perimeter= 10+10+5 cm

p=(4x-2)+(3x+1)+(2x-1)
=9x-2
x=2/9
p=(4*2/9-2)+(3*2/9+1)+(2*2/9+1)
=(8-18)/9+(6+9)/9+(4+9)/9
=-10/9+15/9+13/9
=18/9
=2cm
=9x-2
x=2/9
p=(4*2/9-2)+(3*2/9+1)+(2*2/9+1)
=(8-18)/9+(6+9)/9+(4+9)/9
=-10/9+15/9+13/9
=18/9
=2cm
