The math is pretty straight forward 18 times 18 is 324 square feet
if you are interested in square yards for flooring it would be 18X18=324 then divide by 9 for sq Yard's= 324/9=36 sq yards
in carpet or vinyl a 12'X27 would be enough square feet but would need a bit more for pattern matching and trim waste..
If you are figuring for flooring please remember that 324 is the NET flooring area. some waste is always a part of the project.
A simple rectangular room 20 feet by 18 feet has 360 square feet.
A 10x14 room has an area of 140 square feet (10 feet x 14 feet = 140 square feet).
The area of a 12x10 room is 120 square feet.
The room has a total of 352 square feet (22 x 16 = 352).
A 10x13 room would have 130 square feet. This is calculated by multiplying the length (10 feet) by the width (13 feet) of the room to find the total square footage.
For area measurements, you multiply the length by the width. Here the calculation gives you an answer of 216 square feet.
