A) \[\frac{1}{2}\sqrt{c({{g}^{2}}+{{f}^{2}}-c)}\]
B) \[\sqrt{c({{g}^{2}}+{{f}^{2}}-c)}\]
C) \[c\sqrt{{{g}^{2}}+{{f}^{2}}-c}\]
D) \[\frac{\sqrt{{{g}^{2}}+{{f}^{2}}-c}}{c}\]
Correct Answer: B
Solution :
Area of quadrilateral\[=2\] [area of \[\Delta OAC\]] \[=2.\frac{1}{2}OA\ .\ AC=\sqrt{{{S}_{1}}}.\,\sqrt{{{g}^{2}}+{{f}^{2}}-c}\]You need to login to perform this action.
