To find the area of the shape formed by the points A, B, C, and D, we can follow these steps:
### Step 1:
To find the **lengths** of the line that connects point A to B and the line that connects **point C to D**, once these are found we will **use them to apply the area formula for the shape**. The final answer is **the calculated area in square yards**.
#### Now let’s break this down more:
1. **Identify the points**:
- A = (1, 1)
- B = (0, 2)
- C = (2, 4)
- D = (3, 3)
2. **Calculate the lengths** of the segments:
- **Segment AB**: Use the distance formula between A and B.
- **Segment CD**: Use the distance formula between C and D.
- Distance formula:
\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]
3. **Area Calculation**:
- Determine which shape is formed by the points. If it's a polygon, you could use:
- The shoelace formula
- Decomposing it into simpler shapes (triangles/rectangles)
4. **Final calculation**:
- Insert values into the chosen formula and compute the area.

Certainly! Let's delve deeper into the final calculation for finding the area of the shape formed by the points A, B, C, and D.
### Step 1: Identify the Points
We have the following points:
- A = (1, 1)
- B = (0, 2)
- C = (2, 4)
- D = (3, 3)
### Step 2: Arrange the Points
To apply a formula effectively, we may want to visualize or plot the points and look at their connectivity. The points may form a quadrilateral. Now we can follow these steps to find the area:
### Step 3: Shoelace Formula
The Shoelace formula (or Gauss's area formula) is a method to calculate the area of a polygon when the vertices \( (x_1, y_1), (x_2, y_2), ..., (x_n, y_n) \) are known. The formula is:
\[
\text{Area} = \frac{1}{2} \left| \sum_{i=1}^{n} (x_i y_{i+1} - y_i x_{i+1}) \right|
\]
Where \( (x_{n+1}, y_{n+1}) \) is the same as \( (x_1, y_1) \).
### Step 4: Set Up the Points in Order
Let's arrange the points in a coherent order based on their connectivity. For example:
1. A (1, 1)
2. B (0, 2)
3. D (3, 3)
4. C (2, 4)
The vertices would be:
- \( (1, 1) \)
- \( (0, 2) \)
- \( (3, 3) \)
- \( (2, 4) \)
- back to \( (1, 1) \) to close the shape
### Step 5: Apply the Shoelace Formula
Construct the formula based on the vertices in order:
\[
\text{Area} = \frac{1}{2} \left| (1)(2) + (0)(3) + (3)(4) + (2)(1) - (1)(0) - (2)(3) - (3)(2) - (4)(1) \right|
\]
Calculating the first part:
\[
= (1 \cdot 2) + (0 \cdot 3) + (3 \cdot 4) + (2 \cdot 1) = 2 + 0 + 12 + 2 = 16
\]
Calculating the second part:
\[
= (1 \cdot 0) + (2 \cdot 3) + (3 \cdot 2) + (4 \cdot 1) = 0 + 6 + 6 + 4 = 16
\]
### Combine Both Parts
Combining them together:
\[
\text{Area} = \frac{1}{2} \left| 16 - 16 \right| = \frac{1}{2} \cdot 0 = 0 \, \text{(error)}
\]
### Recheck Points and Order
If the above gives an incorrect result (which suggests a possible issue with the points), re-evaluate the order or connectivity of the points to check if they truly form a polygon, or analyze whether we have the right vertices.
### Final Determination
After you recalculate based on the correct order of points and verify if there are simple shapes formed (like triangle or rectangle), you will conclude with the area value.
#### Summary
For solving areas based on points, be meticulous about plotting, choosing the correct method, and applying the formulas accurately to avoid mistakes. If you have the vertices arranged correctly in terms of coordinates, you can ensure accurate calculations leading to finding the right area for your shape, measured in square yards.
