You will need: 12*24 = 288 square feet
Length x width gives you the area of something. A room for instance. You might have to do this if you were buying a carpet for that room and needed to know what size carpet.
10 ft by 10 ft --- a 4 ft baseboard heater will work. But a longer room may need more. 10 ft by 20 ft would need an 8 foot baseboard heater. etc.
Multiply the length of the room times the width.
To calculate the number of 12x12 tiles needed for a 10x10 room, you first need to find the area of the room. A 10x10 room has an area of 100 square feet. Since each 12x12 tile covers 1 square foot, you would need 100 tiles to cover the entire room.

The square footage of a 12 x 12 room is 144 feet. Most carpet comes in 12 foot width or wider. If it is 12 foot wide you just need a 12 foot piece off the roll. If the carpet is wider, you still have to buy that width and will have some waste.
840 square feet
120 square feet
9 square feet in a sq yard so: its 8X10 to find the area of the room 80 square feet 80 divided by 9 = ? You will also want to know that carpet is made 12' wide so the real question is how much is in a 12X8 ?
each tile is one square foot so you need 55 tiles
