The area of the walk is 15*12 - 12*9 = 72m^2

72m^2 / (.3m)^2 = 800 tiles

Or, you can figure 5 tiles to cross the width of the walk. The garden is 12/.3 = 40 tiles long and 9/.3 = 30 tiles wide.

You will need

two strips of 40x5 on the long side

two strips of 30x5 on the short side

4 corners of 5x5

400+300+100 = 800
