I have an 8x10 concrete slab right now, how much would it cost to pay
someone to extend it to an 12x12 slab? I would only have to add 2ft on
two sides and 4 feet on the other, 4th side is against hte house.

Questions like this are best answered by calling several reputable concrete
contractors in your area and asking for an estimate. It's free, and there's
really no other good way to find out.
