Take note that the 100cm given for rectangle is the perimeter and not the length. the perimeter is the sum of 2 sides of length and 2 sides of the breadth which is 2cm (from the square tiles) so you have to figure out what is the length of the rectangle before dividing it by the length of the square tiles.
