Question

What is the area of a scalene triangle given 3 sides?

Answer 1

Use heron's formula:-

√s(s-a)(s-b)(s-c)

Where s is semi perimeter a,b and c are sides of the scalene ∆

Answer 2

Scalene triangle is a geometric structure that has three dissimilar sides and angles.  

The area of such a triangle cannot be determined like a equatorial triangle.

So that, the area of a scalene triangle can be given as,

 $A=\sqrt{(s)(s-a)(s-b)(s-c))}$

Here s is given as,

$s =\frac{a + b + c}2$  

Where s is termed as the semi perimeter of the triangle.

As in figure their dissimilar sides are denoted by a, b and c which are the lengths of the sides of the scalene triangle. Their corresponding angles will also be different.
