Lu is making a quilt that is 20 squares wide and has 24 rows. the border of the quilt is made by using each design equally as often. each square can hold one design. how many of each design does she use for the border?

Here is the correct answer for this question

The quilt has 4 sides.
The border will have 20 squares two times, and 24 squares two times as well, that is the perimeter or the border.
= 20*2 + 24*2
= 40 + 48
= 88

So, from the answer above, the border will have 88 squares total.
Lu can use any toy design 88 times.
