Is right triangle or not

If right triangle ABC, have sides a=13, b=11.5, c=22.5. Find area.

Correct answer:

A =  54.4151

Step-by-step explanation:

a=13 b=11.5 c=22.5  c1=a2+b2=132+11.5217.3566 c1<>c  s=a+b+c2=13+11.5+22.52=472=2312=23.5  A=s (sa) (sb) (sc)=23.5 (23.513) (23.511.5) (23.522.5)=3 329=54.4151
