Question

What is the area of scalene triangle formula?

Answer 1

hi guy

the answer is here

the are of scalene triangle is


$area = \sqrt{s(s - a)(s - b)(s - c)}$
and " S " stands for semi perimeter.


glad to help you
hope it helps
thank you.

Answer 2

Hey
.
To find the area of a scalene triangle you can use herons formula
.
It states that
$\sqrt{s(s - a)(s - b)(s - c)}$
Where s stands for semi perimeter
.
You can find s by diving the perimeter by 2
.
let's take an example, we have to find the area of a triangle whose sides are 4, 6 and 8
okay?
now
Perimeter = a+b+c = 4+6+8 = 18
S (Semi Perimeter) = 18/2 = 9
.
putting the values in the formula
.
$\sqrt{9(9 - 4)(9 - 6)(9 - 8)}$
$\sqrt{9 \times 5 \times 3 \times 1}$
$\sqrt{135}$
So the area is
$\sqrt{135}$
Hope this helps!
