Shape approximate: the venue publishes area only, so this room is drawn as a square of equal area.
LED wall that fits
Under a 3.1 m ceiling with 1.5 m trim and 0.3 m clearance you get 2 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 55.5 m wall a Absen PL2.5 Plus V2 wall runs 88 x 2 (17600 x 400 px, 1,373 kg, 28.2 kW).

Wall sizing assumes 1.5 m trim to the bottom edge, 0.3 m clearance under the ceiling, and a wall no wider than 80% of the longest wall. Weight and power are tile totals from the panel spec sheet; add processing, rigging, and cable.
