If 1 square foot of tile costs $1.12, what would be the total cost to retile the entire 1800 sq ft room?

To find the total cost to retile the entire 1800 square foot room, you multiply the area of the room by the cost per square foot of tile. In this case, the area is 1800 sq ft, and the cost of tile is $1.12 per sq ft.

Calculating this gives:

Total cost = Area × Cost per square foot
Total cost = 1800 sq ft × $1.12/sq ft = $2016.

Thus, the correct answer reflects the accurate computation of the total cost based on the given measurements and unit price. This clear approach demonstrates how to manage unit pricing and area calculations effectively.
