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.
Well, isn't that just a happy little question! For a 10x10 room, you'll need enough 12x12 tiles to cover the entire floor. Since each tile covers an area of 12x12 square inches, you'll need to calculate the total square footage of the room and then divide by the area of each tile to find the number needed. Just remember, there are no mistakes in art, only happy accidents!

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.
