Using this line as a diagonal; he constructs a square by drawing four more lines. Again, using the side of the square as a diagonal he draws another square. He continues in this manner. He would stop drawing squares once the area of the square becomes less than one-thousandth of the area of the first squareIf instead of squares, he starts making rhombus having 1200 as one the angles taking 16 cm line as the smaller diagonal and proceeds in a similar fashion, then how many rhombi will he make?
