If your peice of concrete does not have beams I consider that flatwork. So in flatwork with 3/8 rebar (#3) on 16" centers, for the 15 foot side you will have 8 pieces x 15' long. On the 10' side you will need 12 pieces x 10'. (6 bars cut in half) In all you will need 14 #3 x 20'

How much concrete will 4 yards cover?
I think you mean "How much area will 4 yards of concrete cover?". It depends on the slab thickness and whether or not anything significant is embedded (a lot of rebar, conduit, etc.). If working in feet, measure the width length and depth, multiply these numbers then divide the result by 27 to calculate the volume in cubic yards. A slab 9' 6" by 10' 4" by 6" thick translates to 9.5x10.3x.5 (48.93) /27 = 1.8 yards. Since you already have the volume, you will need to play with some of the dimensions to find something that works.
