Expert Answer
Let each side of the square be x units.
Dimensions of rectangle obtained by folding the square are
Length of rectange = x units
Breadth of rectangle = x/2 units
Perimeter of rectangle = x + x + x/2 + x/2 = 3x
Since, the perimeter is given as 12
3x = 12
x = 4 units.
Perimeter of square = 4x = 16.
