Help me solve this please $[$Load Path $|$ Test $2$A $|2024]$

The floor framing plan below $($N$.$T$.$S$.)$ consists of a steel deck supported by Open Web Steel Joists $($OWSJ$)$ spaced as shown. The joists are supported by steel I$-$beams, and the beams are supported by steel HSS columns, or by other beams. All joists$/$beams are simply supported at each end. The total factored load on the floor is $3\mathrm{.}2$ kPa $.$

a$.$ Beam B$1$: Calculate the tributary width $[$m$].$ Draw the beam diagram $($include span, supports, loading$).$ Calculate the support reactions $[$kN$]$ at each end.

b$.$ Beam B$2$: Calculate the tributary width. $[$m$]$ Draw the beam diagram $($include span, supports, loading$).$ Calculate the support reactions for Beam B$2.$
