I am not an expert, but I have cooled a 12 x 18 room, 206 sq. ft. with a 9,000 BTU window unit, and it gets hot in Texas. Take it from there.
If it's a square room then the room size is 14 feet by 14 feet
211 square feet is the room size.
260 square feet is the room size.
178 Tiles If the square footage is the actual room size you add 10% for wastee
Imagine a room 25 feet by 13 feet. That room has an area of 25 x 13 or 325 square feet.
400 square feet.
A room that is 12' x 15' would be 180 square feet.
If the numbers provided are inches, then the room contains 228 Square feet.
19.5 by 2.9 feet is the answer
357628574 square feet
Any room where the length in feet times the width in feet equals 718.
You're asking for a measurement of the size of a room and you already have the measurement. 275 square feet is a room that is a bit larger than 16x16 feet.
