Linda this is a square quilt, you are wanting to make a rectangular quilt. You will need to add 26" to the width and 40" to the length.
The blocks are 10&1/2 (10" finished), so you can add 4 blocks to the length and it will measure 112"x82".
The prob is getting the width to 98 unless you can divide the blocks.
I would make the quilt 112"x112", it would be much easier.
