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
