Two sides of a triangle are 12cm and 14cm. The perimeter of the triangle is 36cm. What is its third side?

Given:

Two sides of a triangle are 12cm and 14cm. The perimeter of the triangle is 36cm.

To do:

We have to find the third side.

Solution:

Perimeter of a triangle = Sum of all the sides

Let the third side be $x$.

Therefore,

$(12+14+x)\ cm = 36\ cm$

$x = (36-26)\ cm$

$x=10\ cm$

The length of the third side is $10\ cm$.
