Answer:
The 6 by 5 rectangle
Step-by-step explanation:
It is the 6 by 5 rectangle because the text says she used 22 inches to border the cover. this means we need to look at the rectangles perimeters to find the answer. to find the perimeter of rectangles that only give you measurements for two sides you need to multiply each measurement by 2. So you need to do 6 times 2 and 5 times 2 to get 12 and 10. once you have your two numbers you add them together. 12+10=22. (remember we were looking for a recangle with a perimeter of 22 inches)
I hope this helps you out a little.
