# The lengths of two sides of a triangle are 12 cm and 15 cm. Between what two measures should the length of the third side fall?

**Solution:**

Reasoning:

This question is straightforward.

In this question, two sides of a triangle are given as 12cm and 15 cm, find the sum and difference of these two sides.

Remember, the third side should be lesser than their sum, and also it should be greater than their difference.

The sides of a triangle are given as 12cm and 15 cm.

Hence the third side will be lesser than the sum of these two sides 12 cm + 15 cm = 27 cm.

And also it will be greater than the difference of these two sides 15 cm – 12 cm = 3 cm.

Therefore, the length of the third side will be smaller than 27 cm and greater than 3 cm.
