The first consideration would be whether the length and width will fit exactly across the rectangle.
If possible, you really don't want to be cutting a thin strip off the edge of the last roll and this would be a waste, decide which way they are going to be laid down.
The length of 24m will require 3 rolls, each with a length of 8m.
The width of each roll is 60cm.
To find how many rolls fit across the width :
Therefore 9 rolls across the width and 3 rolls down the length means that exactly
with no wastage and no gaps to be filled.
