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 24.1 m wall a Absen A2 Pro wall runs 38 x 2 (6384 x 336 px, 760 kg, 14.1 kW).
