Answer 2

Answer:

ANSWER

Here, P = 8+15 +17= 21 cm

S=  

2

a+b+c

​  

 

So S=  

2

40

​  

=20cm

s−a=12,s−b=5,s−c=3

Area of triangle=  

S(S−a)(S−b)(S−c)

​  

 

                       =  

20(12)(5)(3)

​  

 

                       =  

40(12)(5)(3)

​  

 

                       =60
