Answer:
According to Heron, we can find the area of any given triangle, whether it is a scalene, isosceles or equilateral, by using the formula, provided the sides of the triangle.

Answer:
Example 1: If the length of the sides of a triangle ABC are 4 in, 3 in, and 5 in. Calculate its area.
Solution: To find: Area of the triangle ABC.
Given that, AB = 4 in, BC = 3 in, AC = 5 in (let)
Using Heron's Formula,
A = √(s(s-a)(s-b)(s-c))
As, s = (a+b+c)/2
s = (4+3+5)/2
s = 6 units
Put the values,
A = √(6(6-4)(6-3)(6-5))
⇒ A = √(6(2)(3)(1))
⇒ A = √(36) = 6 in2
∴ The area of the triangle is 6 in2.
