Answer:
Total cost = $243 for a 9 ft. long square-shaped room
Explanation:
Step 1: First, we need to find the area of the room. The formula for area of a square is:
A = s^2, where
- A is the area in square units,
- and s is the side length
Since the side length is 9 ft, we plug in 9 for s in the area of a square formula:
A = 9 ^2
A = 81 square ft.
Step 2: Since the carpet costs $3.00/square foot, we can multiply 3 by 81 to find the total cost of the carpet:
Total cost = 3 * 81
Total cost = $243
