Heron's Formula

Using Heron's Formula to find the area of a triangle.
Heron's formula is a formula that gives the area of a triangle given the lengths of its three sides. It is named after Heron of Alexandria, a Greek mathematician who lived in the 1st century AD.
The formula is:
A = sqrt(s(s-a)(s-b)(s-c))
where:
A is the area of the triangle
s is the semiperimeter of the triangle, which is half the sum of the lengths of the three sides
a, b, and c are the lengths of the three sides of the triangle
Heron's formula can be derived using trigonometry or geometry. It is a powerful formula that can be used to find the area of any triangle, regardless of its shape or size.
