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
but we're not done!
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
