Answer: it would cost him $1660.16 to buy enough carpet for the room.
Explanation:
The formula for determining the area of a square is expressed as
Area = L²
Where
L represents the length if each side of the square.
The sides of a square-shaped room are 4 meters long. This means that the area of the room is
4² = 16m²
If the carpet that Darnay wants to buy costs $103.76 per square meter, then the amount that it will cost to buy enough carpet for the room is
16 × 103.76 = $1660.16
