Let's analyze the question based on the image you uploaded, which contains a floor plan of the second floor of a house.

We are asked the following:

### a) Determine the scale of the plan and express it in its normalized form.
You are given that the width of the **"Dormitorio Principal"** (Main Bedroom) is **3.7 meters**. By measuring the width of the same room in the given plan (using the image), we can calculate the scale ratio.

### b) Calculate the real dimensions of the second floor (at least the minimum).
To solve this, we'll measure the overall dimensions of the plan in the image, apply the scale from part a), and convert those measurements into real-world dimensions.

### c) Will a 1:30 scale allow for the reproduction of this plan on an A3 sheet (29.7 cm x 42 cm)?
Using the same measurements and converting them to a 1:30 scale, we'll check if the entire floor plan fits on an A3 sheet.

I'll begin by measuring the necessary distances from the image to solve each part. Let me proceed with the calculations.The image has a resolution of **320 x 374 pixels**. I will now proceed to measure the width of the "Dormitorio Principal" (Main Bedroom) in the image to calculate the scale and address part (a) of the question. 

Let me continue by extracting that measurement.The cropped image of the "Dormitorio Principal" has a width of **140 pixels**.

Since the real-world width of this room is **3.7 meters**, we can now calculate the scale of the plan by comparing the pixel width to the actual width.

I'll proceed with the scale calculation.The scale of the plan is approximately **1:37.84**. This means that 1 unit on the plan corresponds to about 37.84 units in real life.

Next, I will proceed to calculate the real dimensions of the second floor based on this scale (for part b).It seems like I can’t do more advanced data analysis right now. Please try again later. 

However, I can guide you through how to proceed:

1. Measure the pixel width and height of the entire floor plan on the image.
2. Multiply these pixel dimensions by the scale ratio (0.02643 meters per pixel) to get the real-world dimensions.
3. To answer part (c), apply the 1:30 scale to the real dimensions, and check if they fit within the dimensions of an A3 sheet (29.7 cm x 42 cm).

Feel free to ask any other questions or let me know if you'd like further clarification on the steps!
