I'm scaling down, here are my values
FROM 27ft x 24ft
TO 4in x 4.1875in

now do the same thing for 
21ft x 18ft

To scale down from 21ft x 18ft, using the same scale factor that takes 27ft x 24ft down to 4in x 4.1875in, we first need to determine the scale factor.

### Step 1: Calculate the scale factor
The scale factor is the ratio between the dimensions of the original and the scaled-down versions. We can calculate it by dividing the scaled-down dimension by the original dimension.

For the width:
\[
\text{Scale Factor for Width} = \frac{4 \text{ in}}{27 \text{ ft}}
\]

For the height:
\[
\text{Scale Factor for Height} = \frac{4.1875 \text{ in}}{24 \text{ ft}}
\]

Since both the width and height should have the same scaling, we can take the average of these two scale factors to get a unified factor to apply to the second set of dimensions.

### Step 2: Apply the scale factor to the new dimensions (21ft x 18ft)

Once we calculate the scale factor, we multiply it by the dimensions 21ft and 18ft to get the new scaled dimensions in inches.

Let me calculate that for you.The scaled-down dimensions for 21ft x 18ft, using the same scale factor as before, are approximately:

- **Width**: 3.39 inches
- **Height**: 2.90 inches

2. What if you had to scale up instead of down—how would the process change?
3. How do different units (e.g., feet to inches) affect scaling calculations?
4. How would you calculate area and perimeter after scaling?
5. Can you scale objects proportionally in three dimensions (volume)?

**Tip:** Always keep units consistent when calculating scale factors to avoid errors.
