A) \[2\,\,r\,\,c{{m}^{2}}\]
B) \[{{r}^{2}}\,\,c{{m}^{2}}\]
C) \[\frac{1}{2}{{r}^{2}}\,\,c{{m}^{2}}\]
D) \[2{{r}^{2\,}}\,\,c{{m}^{2}}\]
Correct Answer: B
Solution :
Let \[\Delta \]ABC is a largest triangle in a semi circle Then, Area of \[\Delta ABC\]=\[\frac{1}{2}\times AB\times CD\] \[=\frac{1}{2}\times 2r\times r\] \[={{r}^{2}}c{{m}^{2}}\]You need to login to perform this action.
