Question

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?​

Answer 1

$\huge\underline\mathrm{SOLUTION:-}$

We know that:

• The sum of the length of any two sides is always greater than the third side.

From the question,

• It is given that two sides of triangle are 12 cm and 15 cm.

So, the third side length should be less than the sum of other two sides,

➠ 12 + 15 = 27 cm.

Then, it is given that the third side is cannot not be less than the difference of the two sides,

➠ 15 - 12 = 3 cm

• So, the length of the third side falls between 3 cm and 27 cm.
