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.
120 square feet
each tile is one square foot so you need 55 tiles
You will need a minimum of 16 square feet of carpet to cover that area.
