A) \[{{s}^{4}}\]
B) \[{{b}^{2}}{{c}^{2}}\]
C) \[{{c}^{2}}{{a}^{2}}\]
D) \[{{a}^{2}}{{b}^{2}}\]
Correct Answer: D
Solution :
\[{{c}^{2}}={{a}^{2}}+{{b}^{2}}\] |
\[\Rightarrow \angle C=\frac{\pi }{2}\] |
\[\therefore \Delta =\frac{1}{2}ab\,\,\sin \,\,C=\frac{1}{2}ab\] |
\[\Rightarrow \sqrt{s\,\,(s-a)\,\,(s-b)\,\,(s-c)}=\frac{1}{2}ab\] |
\[\Rightarrow 4s\,\,(s-a)\,\,(s-b)\,\,(s-c)={{a}^{2}}{{b}^{2}}\] |
