To find the area of the walls that need to be painted in the room, we will calculate the area of each wall and then sum them up.
1. The room has two pairs of opposite walls:
- Two walls are 12 feet wide and 10 feet high.
- Two walls are 14 feet wide and 10 feet high.
2. Calculate the area of the two walls with dimensions 12 feet by 10 feet:
\[
\text{Area of two 12-foot walls} = 2 \times (12 \, \text{ft} \times 10 \, \text{ft}) = 2 \times 120 \, \text{ft}^2 = 240 \, \text{ft}^2
\]
3. Calculate the area of the two walls with dimensions 14 feet by 10 feet:
\[
\text{Area of two 14-foot walls} = 2 \times (14 \, \text{ft} \times 10 \, \text{ft}) = 2 \times 140 \, \text{ft}^2 = 280 \, \text{ft}^2
\]
4. Add the areas of all four walls together:
\[
\text{Total area to paint} = 240 \, \text{ft}^2 + 280 \, \text{ft}^2 = 520 \, \text{ft}^2
\]
Thus, the area that needs to be painted is **520 square feet**.
