b$)$ A saturated undisturbed sample from a clay stratum has moisture content of $22\%$ and specific weight of $2\mathrm{.}7.$ Assuming ${}_w=10k\frac{N}{m^3},$ the void ratio and the saturated unit weight of the clay, respectively are $0\mathrm{.}6$ and $20k\frac{N}{m^3}.$ Determine the consolidation settlement of the clay layer under a square footing $($neglecting its self $-$weight$)$ with additional data shown in the figure $1$ below $($assume the stress distribution as $1H$:$2V$ from the edge of the footing
