143 square feet: between a bedroom and a small living room
Eleven by thirteen works out to 143 sq ft. That is enough for a bedroom with a reading chair, or for a snug living room with a loveseat and two chairs. The 48 ft perimeter is your baseboard length before you subtract the door. Place an 8 × 10 ft rug and there is 1.5 ft of visible floor on each long side and the same 1.5 ft at both ends, an even border that looks deliberate.
Neither side is a multiple of common material sizes, so expect cuts on two walls with tile (158 tiles of 12 in) and a ripped last row with planks. Plank flooring: 8 boxes. Wall paint for two coats: 1.90 gallons over 333 sq ft, bought as 2 gallons.
