The cost of carpet is 3$ per square foot. how much would it cost to carpet a bedroom that is 11ft by 14 ft?

Wouldn't you just multiply both numbers by 3. It says $3 per square foot.It does not matter how long and wide the carpet is.You still have to buy the fabric.Im not sure,but what do you think?

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
