Answer should be $105\mathrm{.}01$ please show working to get that value

The shaded shape is supported by Cable $1$ and Cable $2$ in the position shown $($Drawing is NOT to scale$).$ The shape has a uniform weight per unit area of $10k\frac{N}{m^2}.$

Step $1$: If $A=2\mathrm{.}1m,C=0\mathrm{.}4m,x=1\mathrm{.}2m,y=2\mathrm{.}1m,z=3\mathrm{.}6m,=66,$ and $=14,$ find the value of $B$ needed to keep the shape in static equilibrium. Then solve for the tension in Cable $1($T$1)$ and the tension in Cable $2($T$2).$

Once you have evaluated your values for B$,$ T$1$ and T$2$ it is recommended that you redraw your free body diagram with the correct dimensions, weights, and forces $T{1}_x,T{1}_Y,T{2}_x,T{2}_Y$ and confirm that you do have your problem correctly in horizontal, vertical, and moment equilibrium.

Step $2$: Once you have confirmed that your free body diagram is in equilibrium, solve the following equation: $Z=T1+T2$

Write your final answer for Z $($in kN$)$ in the answer box below. Round your answer to two decimal places.
