$27$ rolls needed

#### Explanation:

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 :

$5.4 m \div 0.6 m = 9$

Therefore 9 rolls across the width and 3 rolls down the length means that exactly

$9 \times 3 = 27$ rolls are needed,

with no wastage and no gaps to be filled.
