QUESTION $1|25$ MARKS$]$

Table The slab as shown in Figure $1$ is to be designed and carries a variable action of $3\mathrm{.}0k\frac{N}{m^2}$ plus floor finishes and ceiling load of $1\mathrm{.}0k\frac{N}{m^2}.$ The characteristic strength of concrete is $30\frac{N}{m}{m}^2$ and for steel is $500\frac{N}{m}{m}^2.$ Assume the concrete cover is $25mm,$ diameter of reinforcement is $10mm$ and concrete density is $25k\frac{N}{m^3}.$ As a design engineer, determine the reinforcement required for the slab.
