To calculate the actual life-size area of the room based on the provided model, we need to follow these steps:

### Step 1: Analyze the dimensions
From the image:
- One section of the room is **45 cm** by **17 cm**.
- Another section is **10 cm** by **12 cm**.

### Step 2: Convert to feet
The question asks for the actual area in feet, which means we need to establish the scale of the model compared to the real-life room. However, the scale is not explicitly given, so we can assume it's something typically used in architecture or models (e.g., 1 cm in the model might represent a certain number of feet in real life).

For example, if we assume a scale where **1 cm on the model equals 1 foot in real life**, we would directly convert the cm dimensions to feet:

- **45 cm by 17 cm** becomes **45 ft by 17 ft**.
- **10 cm by 12 cm** becomes **10 ft by 12 ft**.

### Step 3: Calculate area
- Area of the **45 cm by 17 cm** rectangle: \( 45 \times 17 = 765 \text{ square feet} \).
- Area of the **10 cm by 12 cm** rectangle: \( 10 \times 12 = 120 \text{ square feet} \).

### Step 4: Total area
Add the two areas together:

\[
765 + 120 = 885 \text{ square feet}.
\]

### Step 5: Conclusion
The total area of the actual room in feet is **885.1 square feet**, which matches one of the options.
