Math🤯?
I’m trying to get measurements for a borderfor a 90”x90” quilt.
If I only have one yard what is each strip cut to?
Edited to add yardage is 45”.

If cutting on the length of grain -
I would cut eleven 3-3/4 inch strips = 41-1/4 inches
If one is comfortable cutting 3-7/8 wide strips = that would use up 42.58 inches of width.
Theoretically, one could get eleven 4-inch wide strips from a 45 inch width - but i would go for the slightly narrower width.
11 strips will give you 396 inches total of length - you might want to play with where you want to place the seams.
No matter which way you cut it, you will have to do some piecing to get the needed lengths.
P.S. Those are theoretical measurements - your piece of fabric may not be cut "exactly" straight

I would cut lengthwise strips for three reasons:
1) Lengthwise usually has less stretch
2) The piece may or may not be cut exactly straight/even
3) This will have to pieced anyway, and I think it is easier to cut shorter lengths
How I arrived at those numbers:
Use the perimeter measurements plus four additional border widths plus seam allowances.
Was given the 90 inch measurements and decided to use 4 as a border width guess and used 6 for seam allowances
(90 + 90 + 90 + 90 + 4 + 4 + 4 + 4 + 6) = 380
Divide 380 (approximate total length needed) by 36; approximate length of fabric available
380 / 36 = 10.55....
So - I would need to cut 11 strips - which would give me 396 inches of length
Then I would start multiplying various numbers by 11 to see what I come up with:
4 x 11 = 44 (too close for my comfort - let's try something narrower)
3-7/8 x 11 = 42-5/8 - I can deal with that
3-3/4 x 11 = 41-1/4
These numbers are theoretical -

2) The piece may or may not be cut exactly straight/even

Whether they are cut lengthwise or crosswise from a piece of fabric that is 36 inches long by 42 to 45 inches wide.
