Formula

Heron's Formula is given by:

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

where

s is the semi-perimeter of the triangle

a,b,c, are the lengths of its sides.

Examples:

Example 1:

For a triangle with side lengths a=5, b=12, and c=13. Find the area.

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

$s = \frac{30}{2}$

s = 15

$area = \sqrt{15 (15 - 5) (15 - 12) (15 - 13)}$

Area = 30 square units

Example 2:

For a triangle with side lengths a=7, b=24, and c=25. Find the area.

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

$s = \frac{56}{2}$

s = 28

$area = \sqrt{28 (28 - 7) (28 - 24) (28 - 25)}$

Area = 84.017 square units

Frequently Asked Questions

Can Heron's Formula be used for all types of triangles?

Yes, Heron's Formula is applicable to all types of triangles, including equilateral, isosceles, and scalene.

What happens if the given side lengths do not form a triangle?

If the given side lengths do not satisfy the triangle inequality theorem, the calculator will indicate that it's not a valid triangle.

Can Heron's Formula be used to find the area of a right-angled triangle?

Yes, Heron's Formula can be used for right-angled triangles as well as other types, as long as the side lengths are known.

What is the Triangle Inequality Theorem?

The sum of the lengths of any two sides of a triangle must be greater than the length of the remaining sides.
