A) \[200\sqrt{2}\text{ }sq\text{ }m\]
B) \[400\sqrt{2\,}\,sq\,m\]
C) \[400\,\,sq\,m\]
D) \[800\,\,sq\,m\]
Correct Answer: C
Solution :
| [c] Side of given square \[=\sqrt{200}\,m\] \[=10\sqrt{2\,}\,m\] It's diagonal \[=10\sqrt{2}\times \sqrt{2}=20\,\,m\] which is the side of new square \[\therefore \]Area of new square \[={{(20)}^{2}}=400\,sq\,m\] |
