The Area of Triangle Calculator is an invaluable tool used to compute the area enclosed within a triangle given the lengths of its three sides—often denoted as 'a', 'b', and 'c'. It employs Heron's formula, a mathematical equation allowing users to swiftly determine the triangle's area without complex manual calculations.
Formula of Area of Triangle Calculator
To ascertain the area of a triangle, Heron's formula comes into play:
s = (a + b + c) / 2
A = √(s * (s - a) * (s - b) * (s - c))
Here, 's' represents the semi-perimeter of the triangle while 'A' signifies the area. By inserting the known side lengths into this formula, users can easily determine the triangle's area.

Example of Area of Triangle Calculator
Consider a triangle with side lengths 'a' as 5 units, 'b' as 7 units, and 'c' as 8 units. Utilizing Heron's formula:
s = (5 + 7 + 8) / 2 = 20 / 2 = 10
A = √(10 * (10 - 5) * (10 - 7) * (10 - 8)) = √(10 * 5 * 3 * 2) = √(300) ≈ 17.32 square units
Therefore, the area of the given triangle is approximately 17.32 square units.
