A piece of cardboard is 20 m long and 9 m wide. Joyce cuts square pieces from it. If each square piece has a side of 2 m, how many pieces would Joyce get?

40 squares


The length is 20 m so divide 20 by 2 to see how many squares you can fit along its length.


The width is 9 m so if you divide 9 by 2 this will tell you how many squares across the width.


You can fit 10 squares along its length and 4 squares across its width. So if you can fit 10 rows, 4 times that would be 40 squares

There would be a length 1 m by 10 m of waste.
Hope this is clearer.
