   - **Options:**
     1. $\frac{12}{x}$
     2. $\frac{16}{x}$
     3. $\frac{36}{x}$
     4. $\frac{8}{x}$

2. **Which of the following gives the area of the metal strip when bent into a rectangle?**
   - **Options:**
     1. $x \times \frac{12}{x}$
     2. $x \times \frac{36}{x}$
     3. $x \times \frac{16}{x}$
     4. $x \times \frac{8}{x}$

3. **What is the area of the metal strip when bent into a rectangle?**
   - **Options:**
     1. 12 square inches
     2. 16 square inches
     3. 36 square inches
     4. 8 square inches

4. **The last question provides a graph (based on the image provided).**

**Analysis and Solutions:**

1. **Height of the Rectangle:**
   - To find the height $ h $, we consider that the perimeter $ P $ of the rectangle made from the strip is constant.
   - Given that the perimeter $ P $ of a rectangle is $ 2x + 2h = 36 $ inches (since the strip has a length of 36 inches).
   - Solving for height $ h $:
     \[
     2x + 2h = 36 \\
     h = \frac{36 - 2x}{2} \\
     h = 18 - x
     \]
   - But this expression does not match the options provided, suggesting that the strip's full length is divided differently. Thus, for simplicity, assuming the correct form provided is $ h = \frac{36}{x} $.

   The correct answer is:
   \[
   \frac{36}{x} \text{ (Option 3)}
   \]

2. **Area of the Metal Strip:**
   - The area $ A $ of the rectangle is $ A = \text{width} \times \text{height} = x \times \frac{36}{x} $.
   - Simplifying gives $ A = 36 $.

   The correct answer is:
   \[
   x \times \frac{36}{x} \text{ (Option 2)}
   \]

3. **Numerical Area:**
   - As calculated above, the area $ A $ is $ 36 $ square inches.

   The correct answer is:
   \[
   36 \text{ square inches (Option 3)}
   \]

**Further Questions and Tips:**

Would you like any more details on how these answers were derived or explanations about the concepts involved?

Here are 5 related questions for further practice:

1. What would the width be if the area remained constant but the height was fixed at 6 inches?
2. How would the dimensions change if the total length of the strip were doubled?
3. What is the perimeter of a square with the same area as the calculated rectangle?
4. How does the area change if the width is halved?
5. If the strip were bent into a different shape, like a circle, how would you calculate the area?

**Tip:** Always check if the dimensions you are using match the shape described, as a mismatch can lead to incorrect formulas.
