19. A room is 13.5 feet long by 10 feet wide. Carpet costs $2.75 per
square foot. How much does it cost to carpet the room?

$371.25

Step-by-step explanation:

First, find the area of the room

a=length * width

a=13.5*10

a=135 feet^2

Multiply the area by the price/foot^2

135*2.75

371.25

So, it cost $371.25 to carpet the room

Hope this helps! :)
