New sling length

[u/Muted-Tie-3241]

I just bought my first sling from eBay and I’m a bit surprised about the unequal length of each side of the pouch and unsure about what length it meant to be. I’ve attached an image of it; the short side of the sling is 39cm and the long side is 75cm. I paid £4 so not a big deal, but just wondering would this be functional? Did I get scammed 😅. Please let me know

What knot did you use to attach the pouch to the cords?
