**Reiny**, Tuesday, July 24, 2012 at 12:30amlet's assume the paper is rectangular of length x and width y

Dividing the length by 5 and the width by 5 will give us our 25 similar pieces

original perimeter = 2x + 2y = 2(x+y)

perimeter of one small piece = 2(x/5) + 2(y/5)

= (2/5)(x+y)

so perimeter of a small piece / perimeter of original

= (2/5)(x+y)/(x+y)

= 2/5
