Hy mate Answer of this is here !!

Step-by-step explanation:

The formula of perimeter of triangle  is

= Sum of three side  

a) 3cm , 4cm , 5cm

Answer= Perimeter of triangle  

             = Sum of three side  

              = 3 + 3 + 3

             = 9 cm  

= Perimeter of triangle  

             = Sum of three side  

              = 4 + 4 + 4

             = 12 cm  

= Perimeter of triangle  

             = Sum of three side  

             = 5 + 5 + 5

             = 15 cm  

b) 11cm , 12cm , 13cm

Answer= Perimeter of triangle  

             = Sum of three side  

              = 11 + 11 + 11

             = 33 cm  

= Perimeter of triangle  

             = Sum of three side  

              = 12 + 12 + 12

             = 36 cm  

= Perimeter of triangle  

             = Sum of three side  

             = 13 + 13 + 13

             = 39 cm  

c) 50cm , 40cm , 60cm

Answer= Perimeter of triangle  

             = Sum of three side  

              = 50 + 50 + 50

             = 150 cm  

= Perimeter of triangle  

             = Sum of three side  

             = 40 + 40 + 40

             = 120 cm  

= Perimeter of triangle  

             = Sum of three side  

              = 60 + 60 + 60

             = 180 cm  

Thanks,

Have A Great Day !!
