B) 60 cm
C) 160 cm
D) None of these
Correct Answer: D
Solution :
Breadth of rectangle \[=25\frac{1}{5}\,\,\,\,1=4\] cm \[\therefore \] Area of rectangle = length breadth \[=25\,\,\,\,4=100\] sq.cm. \[\therefore \] Area of square \[=4\,\,\,100\,=400\] sq.cm. \[\therefore \] Side of square \[=\sqrt{400}\,\,=20\] cm. \[\therefore \] Perimeter of square = 4 side \[=4\,\,\,\,20=80\] cm.You need to login to perform this action.
