Answer:
B
Step-by-step explanation:
So if she sews along the edge, that means 144 is the perimeter,
The shape is a rectangle, therefore 2 of the sides are 37,
You should add 37 to 37 and that will give you 74
Subtract 74 from 144 to get 70
<em>but we're not done!</em>
The question asked for the length of the quilt, but we only subtracted the length from the total perimeter!
Now you must divide by 2 and you should get 35 inches
