A) \[2\sqrt{30}\,\text{m}\]
B) \[\sqrt{13}\,\text{m}\]
C) 13 m
D) \[8\sqrt{15}\,\text{m}\]
Correct Answer: A
Solution :
Length of garden\[=12\,m\] and breadth of garden\[=5\,m\] \[\therefore \] Area of square garden\[=12\times 5=60\,{{m}^{2}}\] \[\therefore \] Area of square garden\[=60\,{{m}^{2}}\] Side of this square garden\[=\sqrt{60}=2\sqrt{15}\] \[\therefore \] Length of diagonal of square garden \[=2\sqrt{15}\times \sqrt{2}=2\sqrt{30}\,m\]
