Question

jessica wants to buy new carpet for her living - room floor. the floor is in the shape of a rectangle. its length is 19 feet and its width is 12 feet. suppose carpet costs $8 for each square foot. how much will carpet cost for the floor?

Explanation:

Step1: Calculate floor area

The area formula for a rectangle is $A = l\times w$, where $l = 19$ feet and $w = 12$ feet. So $A=19\times12 = 228$ square - feet.

Step2: Calculate total cost

The cost per square - foot is $\$8$. So the total cost $C$ is $C = 8\times A$. Substitute $A = 228$ into the formula, we get $C=8\times228 = 1824$.

Answer:

$1824$
