The perimeter of an isosceles triangle is 32 cm while its equal sides together measure 18 cm. Find the length of the other side

Solution

✅ Correct Option: 2

An isosceles triangle has 2 equal sides and 1 different side.

The perimeter is 32 cm and the 2 equal sides together measure 18 cm.


The perimeter of a triangle is all three sides added together:

Perimeter = Equal side + Equal side + Third side

This can be written as:

Perimeter = (Both equal sides together) + Third side


Substituting the known values:

32=18+Third side32 = 18 + \text{Third side}

Third side=32−18\text{Third side} = 32 - 18

Third side=14\text{Third side} = 14

Therefore, the length of the other side is 14 cm.
