Let's find the length of the rectangle using the width we just calculated.

### Given:
- The width \( w = 6.1 \) inches.
- The length \( L \) is 3 inches less than 4 times the width.

### Length Formula:
\[
L = 4w - 3
\]

### Substitute the Width:
\[
L = 4(6.1) - 3
\]
\[
L = 24.4 - 3
\]
\[
L = 21.4 \text{ inches}
\]

### Final Answer:
The length of the rectangle is **21.4 inches**.

2. How would the length change if the width were decreased by 1 inch?
3. If the length were increased by 5 inches, what would be the new perimeter?
4. How would you find the diagonal of the rectangle?
5. What would happen to the length if the perimeter was fixed at 55 inches, but the width was increased?

**Tip:** Understanding the relationship between length, width, and perimeter is crucial in solving rectangle-related problems quickly.
