Question

kevin wants to buy new carpet for his living - room floor. the floor is in the shape of a rectangle. its length is 18 feet and its width is 11 feet. suppose carpet costs $9 for each square foot. how much will carpet cost for the floor?

Explanation:

Step1: Calculate floor area

The area $A$ of a rectangle is $A = l\times w$, where $l = 18$ feet and $w = 11$ feet. So $A=18\times11 = 198$ square - feet.

Step2: Calculate total cost

The cost per square - foot is $\$9$. So the total cost $C$ is $C=A\times9$. Substitute $A = 198$ into the formula, we get $C=198\times9=1782$.

Answer:

$1782$
