Question 1177674
Let's break down this problem:

**1. Understand the Dimensions**

* **Model Side:** 28 meters
* **Intended Building Side:** 2,805 meters

**2. Calculate the Ratio**

The ratio we need is the model side length to the intended building side length:

* Ratio = (Model Side) / (Intended Building Side)
* Ratio = 28 m / 2,805 m

**3. Simplify the Ratio**

Now, let's simplify the fraction:

* 28 / 2,805 ≈ 0.009982174688057042

**4. Express the Ratio**

We can also express this ratio as a fraction.

* 28/2805. We can simplify this fraction by dividing both numerator and denominator by their greatest common divisor, which is 1. Therefore the simplest form of the ratio is 28/2805.

**Answer**

The ratio of the square base of the model to the length of the base side of the intended building is approximately 0.009982 or 28/2805.
