From the picture, you can see that in order to go all the way around,
she'll need 4-2/3 yards twice, and 6-3/4 yards twice.
That's called the 'perimeter' of the rectangle. It's always (2 lengths) + (2 widths).
I just gave you the addition problem. Add up the mixed numbers, and see
whether the perimeter is more or less than 22 .
