A city generates $40 \times 10^{6} \mathrm{~kg}$ of municipal solid waste (MSW) per year, out of which only $10 \%$ is recovered/recycled and the rest goes to landfill. The landfill has a single lift of $3 \mathrm{~m}$ height and is compacted to a density of $550 \mathrm{~kg} / \mathrm{m}^{3}$. If $80 \%$ of the landfill is assumed to be MSW, the landfill area (in $m^{2}$, up to one decimal place) required would be
