Heron’s formula is used to find the area of a scalene triangle only.

Concept: If a triangle has three sides, a, b, and c, semi-perimeter, s, and area of triangle A, then the semi-perimeter and area of the triangle are given as:

$\text{s}=\frac{\text{a}+\text{b}+\text{c}}{2}$

Area of triangle$=\sqrt{\text{s}(\text{s}-\text{a})(\text{s}-\text{b})(\text{s}-\text{c})}$

According to the definition of Heron’s formula, it can be used to find the area of a triangle when we know the length of all its sides.

We can calculate the area of any triangle, whether it is scalene, isosceles, or equilateral.

Hence, the given statement is false.
