Answer:
Width = 66 inches
Explanation:
Zelda has 300 inch roll of binding for a quilt.
The length must be 84 inches
We need to find its width. Let it is b.
Let us assume that the quilt is in the shape of rectangle. The perimeter of the rectangle is given by :
P = 2(l+b)
300 = 2(84+b)
150 = 84+b
b = 150-84
b = 66 inches
So, the required width is 66 inches.
