Detailed Solution

Concept- In order to solve the given problem , we have given the length of three sides of a triangle then we put the value in the formula of perimeter of triangle= (a + b + c) cm. where a, b, c are sides of triangle and we get the answer.
Here,

a = 14 cm

b = 17 cm

c = 25 cm

Then,

perimeter of triangle = (a + b + c)

Therefore by putting the value of a, b, c ,we will get

= (14 + 17 + 25) cm

= 56 cm

Hence, the correct answer is option 2.
