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
