Question

mary 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 the area of the rectangle

The formula for the area of a rectangle is \( A = length \times width \). Given length \( l = 19 \) feet and width \( w = 12 \) feet. So, \( A = 19\times12 \)
\( 19\times12 = 228 \) square feet.

Step2: Calculate the total cost of the carpet

The cost per square foot is $8. So total cost \( C = area\times cost\ per\ square\ foot \). Substituting the values, \( C = 228\times8 \)
\( 228\times8 = 1824 \)

Answer:

The carpet will cost $1824.
