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

14 cm

The correct answer is Option (2) → 14 cm

Step-by-Step Calculation:

Understand the Properties:

An isosceles triangle has two equal sides and one base (the "other side").

Use the Perimeter Formula:

The perimeter of a triangle is the sum of all its three sides.

$\text{Perimeter} = (\text{Sum of equal sides}) + (\text{Length of the other side})$

Plug in the Given Values:

• $\text{Perimeter} = 32 \text{ cm}$

• $\text{Sum of equal sides} = 18 \text{ cm}$

Solve for the Other Side:

$32 = 18 + \text{Other side}$

$\text{Other side} = 32 - 18$

$\text{Other side} = \mathbf{14 \text{ cm}}$
