Find the cost of carpeting a room 13m by 9m with a carpet of width 75cm at the rate of 105per metre.
105 what
To find the cost of carpeting a room, follow these steps:
Step 1: Calculate the area of the room.
To find the area of the room, multiply the length by the width:
Area = length × width
Area = 13m × 9m
Area = 117m²
Step 2: Calculate the total length of carpet required.
Since the carpet has a width of 75cm (which is 0.75m), we need to calculate the total length required by dividing the area by the width:
Total Length = Area ÷ Width
Total Length = 117m² ÷ 0.75m
Total Length = 156m
Step 3: Calculate the cost of carpeting.
The rate of carpeting is $105 per meter, so the cost can be calculated by multiplying the total length by the rate:
Cost = Total Length × Rate
Cost = 156m × $105/m
Cost = $16,380
Therefore, the cost of carpeting the room is $16,380.
