<h3 /><h3>What is Heron's formula in math?</h3>
- Heron's formula, formula credited to Heron of Alexandria for finding the area of a triangle in terms of the lengths of its sides.
- In symbols, if a, b, and c are the lengths of the sides: Area = Square root of√s(s - a)(s - b)(s - c) where s is half the perimeter, or (a + b + c)/2.
we know that
The formula of area of triangle is equal to
![A = \frac{1}{2} (b) (h)](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%28b%29%20%28h%29)
We have
b = BC = 6 in
h = AD = x in
substitute
![A = \frac{1}{2} (6) (x)](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%286%29%20%28x%29)
![A = 3x^{2} in^{2} ..................(1)](https://tex.z-dn.net/?f=A%20%3D%203x%5E%7B2%7D%20%20%20in%5E%7B2%7D%20..................%281%29)
Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.
Let a,b,c be the lengths of the sides of a triangle.
The area is given by:-
where p is half the perimeter
![p = \frac{a +b+ c}{2}](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7Ba%20%2Bb%2B%20c%7D%7B2%7D)
a = 9 in , b= 9 in, c = 6 in
![p = \frac{9 + 9 + 6}{2} = 12 in](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7B9%20%2B%209%20%2B%206%7D%7B2%7D%20%3D%2012%20in)
Find the area
![A = \sqrt{12( 12 - 9) (12-9) (12 - 6)}](https://tex.z-dn.net/?f=A%20%3D%20%5Csqrt%7B12%28%2012%20-%209%29%20%2812-9%29%20%2812%20-%206%29%7D)
![A = \sqrt{12 (3)(3)(6)}](https://tex.z-dn.net/?f=A%20%3D%20%5Csqrt%7B12%20%283%29%283%29%286%29%7D)
![A = \sqrt{648}](https://tex.z-dn.net/?f=A%20%3D%20%5Csqrt%7B648%7D)
![A = 25.46 in^{2}](https://tex.z-dn.net/?f=A%20%3D%2025.46%20in%5E%7B2%7D)
Substitute the value of the area in the equation 1 and solve for x
![A = 3x in^{2}](https://tex.z-dn.net/?f=A%20%3D%203x%20in%5E%7B2%7D)
25.46 = 3x
x = 25.46/3
x = 8.5 in
