A concrete floor slab measuring $6800mm3200mm$ is simply supported on one side by $230mm$ brick load bearing walls along the $6800mm$ sides. The concrete slab is $200mm$ thick and reinforced at the bottom as follows.

Main reinforcement $($short span i$.$e the bars are parallel to the short span$),Y12,$ shape code $34$ @ $125$ mm centre to centre,

Distribution reinforcement $($long span i$.$e the bars are parallel to the long span$),$ Y $10,$ shape code $20$ @ $300$ mm centre to centre,

Concrete cover, $30mm,$

Concrete strength, $40$MPa.

Where necessary, use valid assumptions for information not provided.

$1\mathrm{.}1.$ Draw the reinforcement layout for this slab, in plan and section, indicating all the reinforcement and necessary information required by the contractor. Your drawing must be neat.
