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