A) \[8\sqrt{2}\,\text{cm}\]
B) 16 cm
C) \[\sqrt{32}\,\text{cm}\]
D) 8 cm
Correct Answer: D
Solution :
Length of diagonal of square \[=452\,cm\] \[\therefore \] Side of square \[=4\,cm\] \[\therefore \] Area of square \[16\,c{{m}^{2}}\] \[\therefore \] Area of another square \[=32\,c{{m}^{2}}\] \[\therefore \] Side of this square \[=\sqrt{32}=4\sqrt{2}\] \[\therefore \] Diagonal of this square \[=4\sqrt{2}\times \sqrt{2}=8\,cm.\]
