Hong wants to buy new carpet for his living room floor. The floor is in the shape of a rectangle. Its length is 15 feet and its width is 9 feet. Suppose carpet costs 13 for each square foot. How much will carpet cost for the floor?
multiply the area by the cost per ft^2
watch the units: ft^2 * $/ft^2 = $
To calculate the cost of the carpet for a rectangular floor, you need to find the area of the floor and then multiply it by the cost per square foot.
The area of a rectangle can be calculated by multiplying its length by its width. So in this case, the area of the floor is:
Area = Length * Width
Area = 15 feet * 9 feet
Area = 135 square feet
Given that the cost of the carpet is $13 for each square foot, you can now multiply the area by the cost per square foot to find the total cost of the carpet:
Cost = Area * Cost per square foot
Cost = 135 square feet * $13 per square foot
Cost = $1,755
Therefore, the cost of the carpet for Hong's living room floor will be $1,755.
