Question

9. Find the value of
$\sqrt{s(s - a)(s - b)(s - c}$
, given a=15, b=18, c=12, and s=1/2(a+b+c).​

Answer 1

Answer of a=15,b=18&c=12

Answer 2

answer:-

89.294

Step-by-step explanation:

S=(15+18+12)/2

=45/2

S=22.5

Now,

S-a= 22.5-15= 7.5

S-b= 22.5-18= 4.5

S-c= 22.5-12= 10.5

√s(s-a)(s-b)(s-c)

=√22.5×7.5×4.5×10.5

= 89.294
