Ez up Tent Already owned

Found out the other day, my ez up tent is not in fact 10 x 10, its only 8 by 8. Put a huge dent in my plans to build a shelter. Really wanted 100sq feet, not 64 sq feet. I do have 2 of them, so that would give me 128 sq feet if I combine them, but that would make joining the roofs a bit tricky for me. The extra 28 sq feet would make it bigger for us to live in. Might make the bathroom inside along with solar shower area as well.
