Assuming that the "binding" goes along the edge of the quilt, the perimeter of the quilt must be at most 300 inches.

If the length of the quilt is 84 inches, then the perimeter is:

P = 2(84) + 2w

where w is the width of the quilt.

Setting the perimeter equal to the maximum value of 300 gives:

2(84) + 2w = 300

2w + 168 = 300

2w = 300 - 168

2w = 132

w = 132 / 2

w = 66 inches

The maximum width of the quilt is 66 inches.
