To determine the area of a room with dimensions 10 feet by 20 feet, we need to convert these dimensions to meters and then calculate the area in square meters.
1. Start by converting the length and width from feet to meters. The conversion factor is \(1 \text{ foot} = 0.3048 \text{ meters}\).
2. Convert the length:
- Length: 10 feet \(\times 0.3048 \text{ meters/foot} = 3.048 \text{ meters}\)
3. Convert the width:
- Width: 20 feet \(\times 0.3048 \text{ meters/foot} = 6.096 \text{ meters}\)
4. Now, calculate the area in square meters:
- \( \text{Area} = \text{Length} \times \text{Width} \)
- \( \text{Area} = 3.048 \text{ meters} \times 6.096 \text{ meters} \approx 18.58 \text{ square meters}\)
Therefore, the approximate area of the room in square meters is 19 m².
The best answer is:
O C. 19 m²
