A) \[35\sqrt{2}\,m\]
B) \[175\sqrt{2}\,m\]
C) 490 m
D) \[5\sqrt{2}\,m\]
Correct Answer: A
Solution :
Let breadth of plot = x m \[\therefore \] length = 5x m According to question, \[\frac{5{{x}^{2}}}{2}=245\] \[\Rightarrow \] \[{{x}^{2}}=\frac{245\times 2}{5}=98\] \[\therefore \] \[x=7\sqrt{2}\,m\] \[\therefore \] Length \[5\times 7\sqrt{2}=35\sqrt{2}\,m\]You need to login to perform this action.
