x+6=5x-2=>4x=8=>x=2. So perimeter of a triangle is x+6+5x-2+7x+4=>13x+6-6=>13x=26cm is your perimeter .

so x+6 = 5x-2
6+2=5x-x
8 = 4x
2= x
value of x is 2
perimeter = x+6+5x-2+7x-4
= 13x+6-6
= 13x put value of x Is 2
= 13*2
= 26 is your ans
6+2=5x-x
8 = 4x
2= x
value of x is 2
perimeter = x+6+5x-2+7x-4
= 13x+6-6
= 13x put value of x Is 2
= 13*2
= 26 is your ans
