Question

If ‘S’ is a perimeter of triangle then according to heron’s formula area of triangle is …..​

Answer 1

Answer:

Step-by-step explanation:

B

s(s−a)(s−b)(s−c)

​

 

Using herons formula, we first have to find the semi perimeter with sides a,b and c:

s=  

2

a+b+c

​

 

And then area of the triangle is:

A=  

s(s−a)(s−b)(s−c)

​

 

Hence, area of a triangle by heron's formula is A=  

s(s−a)(s−b)(s−c)
