Trigonometric Equations Question 345
Question: If $ c^{2}=a^{2}+b^{2} $ , then $ 4s(s-a)(s-b)(s-c)= $
[EAMCET 1986; Pb. CET 1990]
Options:
A) $ s^{4} $
B) $ b^{2}c^{2} $
C) $ c^{2}a^{2} $
D) $ a^{2}b^{2} $
Show Answer
Answer:
Correct Answer: D
Solution:
- $ \Delta $ is right angled, $ \angle C=90^{o} $
$ \therefore 4{{\Delta }^{2}}=4{{( \frac{1}{2}ab )}^{2}}=a^{2}b^{2} $ .
