A) 40 cm.
B) 60 cm.
C) 160 cm.
D) Cannot be determined
E) None of these
Correct Answer: E
Solution :
Breadth of rectangle \[=25\times \frac{1}{5}-1=4cm\] \[\therefore \]Area of rectangle = length \[\times \]breadth \[=25\times 4=100\]sq.cm. \[\therefore \]Area of square \[=4\times 100=400\]sq.cm. \[\therefore \]Side of square \[=\sqrt{400}=20\]cm. \[\therefore \]Perimeter of square \[=4\times \]side \[=4\times 20=80cm.\]You need to login to perform this action.
