Which of the following can be the length of the third side of a triangle whose two sides measure 18 cm and 14 cm
a. 4 cm
b. 3 cm
c. 5 cm
d. 32 cm

Solution:

Given, the length of two sides of a triangle are 18 cm and 14 cm.

We have to find the length of the third side of the triangle.

We know that the sum of the lengths of any two sides of a triangle is always greater than the length of the third side.

Sum of two sides = 18 + 14

= 32 cm

We know that the third side must be greater than the difference between two sides and less than the sum of two sides.

Difference of two sides = 18 - 14

= 4 cm

So, the third side must be greater than 4 cm and less than 32 cm.

Therefore, the third side is 5 cm.
