answer everything except for number $1$ on the picure!!!!!!!!

Design The reinforced

concrete slabs $1$ to $4,$

showing your calculations

for

a$.27\mathrm{.}5$ MPA

b$.24\mathrm{.}0$MPA

Sketch the reinforcement

for the preferred

arrangement showing over

support and bottom

reinforcements. For slabs:

a$.$ Slabs $1,3,4,5$ :

continuous on three

sides and

discontinuous on

one side

b$.$ Slab $2$: cantilevered

c$.$ Slab $6$: continuous on two sides and discontinuous on two sides

What's the estimated weight of steel and volume of concrete for the slab
