Answer 2

Answer:

10 cm

Step-by-step explanation:

We are given that Two sides of a triangle is 12cm and 14 cm.

Let the third side be x

Perimeter of triangle = Sum of all sides

Since we are given that The perimeter of a triangle is 36cm.

So, $36=12+14+x$

$36=26+x$

$36-26=x$

$10=x$

Hence the length of the third side is 10 cm
