Divide 2 = meters by meters. You will get
= = = 11 = 11.
It means that 12 square stones is enough (and even more than enough) for the path,
while 11 square stones are not enough.
From it, made your own conclusion.

@MathLover1 interprets the problem as if there are TWO paths to pave.
You decide which interpretation is correct.
