a = 13
b= 14
a+b+c=36
c = 36 - 13-14 = 36 - 27 = 9
b= 14
a+b+c=36
c = 36 - 13-14 = 36 - 27 = 9

Hello Dear!!!!
Here's your answer....
The given sides are 13 and 14
semiperimeter is 18
Let,
a.b.c are sides
a is 13
b is 14
perimeter = (a+b+c)
semiperimeter = a+b+c/2
perimeter = 2(semiperimeter)
perimeter = 2(18)
perimeter = 36
a+b+c = 36
14+13+c = 36
27 + c = 36
c= 36-27
c = 9
The length of 3rd side is 9cm
