Sagot :

Answer:

Out of 6 designs 4  designs will have 12 repetitions and 2 designs will have 11 repetitions.

Or

On the average each design will be repeated 11.67 times.

Step-by-step explanation:

HEre the width = 20 and length = 15

The perimeter = 2(l+b)

                         = 2( 20+ 15) = 70

The border of the quilt has 70 squares. Each square can have 1 design and there are 6 designs

Number of repetitions for each design = 70/6= 11. 67

6 designs can have 11 repetitions for 66 boxes=  6 *11= 66

4 squares will be left out. 70-66= 4

4  design can have  additional repetition.

Meaning out of 6 designs 4  designs will have 12 repetitions and 2 designs will have 11 repetitions.

Or

On the average each design will be repeated 11.67 times.
