Since the smaller square will be half the size of the bigger square the perimeter is also half which is 4s or 4*2=8cms

In a square diagonal=side√2
the bigger square side is the diagonal of the smaller scale
Let the side of the small square be X then diagonal be X√2
4=X√2
X=4÷√2
X=4×√2÷√2×√2
X=4√2÷2
X=2√2
therefore the side of the square is 2
perimeter of the square is 4Xside
=4X2
=8cm
