A series of perpendicular offsets taken from a curved boundary wall to a straight survey line at an interval of $6 \mathrm{~m}$ are $1.22,1.67,2.04,2.34,2.14,1.87,$ and $1.15 \mathrm{~m}$. The area (in $m^{2}$, round off to 2 decimal places) bounded by the survey line, curved boundary wall, the first and the last offsets, determined using Simpson's rule, is
