Design a suitable RC slab section required to support an imposed load of $2\mathrm{.}5$ kN$/$m$^2$ along with live load of $2$ kN$/$m$^2.$ The slab is being provided over a span of $3$ m c$/$c$.$ Fe$500$ grade steel is locally available near the construction site.

Also, draw a neat section showing the slab reinforcement and its dimensions.
