Question

if the side of triangle 16 12 and 20 cm find out are of triangle​

Answer 1

Answer:

Sides of triangle a=12cm, b=16cm and c=20cm

s=  

2

a+b+c

​  

=  

2

12+16+20

​  

=  

2

48

​  

=24cm

Using Heron's formula,

Area of a triangle=  

s(s−a)(s−b)(s−c)

​  

 

=  

(24−12)(24−16)(24−20)

​  

 

=  

(12)(8)(4)

​  

 

=  

4×3×4×3×4

​  

 

=4×3×2=24sq.cm
