Hello Dear!!!

Here's your answer...

When all the three sides of a triangle are given,
then you can use herons formula...

Let,

s be the perimeter of the triangle.

a,b,c be the sides of the triangle.

The formula is

√s *(s-a)*(s-b)*(s-c)

Hope This helps you....

Answer 2

If it will a right angled triangle,

Area will be,

=> (product of small sides)/2

==================

If any other triangle,

By heren's formula,

Semi perimeter = s

Sides are, a, b, and c


Now

Area = √{s (s -a) (s-b) (s-c)}




I hope this will help you
