Dan takes ruler and measure the width of the piece of paper and finds that the actual width is 48.8cm.

Find the width of each strip.

Missing info?? How many equal strips did Dan cut?

20.3

@all the people, there are 20 strips. I googled it.

To find the width of each strip, we need to know how many strips there are and the total width of the paper.

Unfortunately, you haven't provided the number of strips. Could you please provide that information?
