To find the area of the rectangle defined by the points A(-4,1), B(-2,4), C(4,0), and D(2,-3), we can follow the steps outlined below:
**Step 1:** Find the **length** of the line that connects C to D and the line that connects **A to B**.
Once these are found, we will **multiply** these.
The final answer is approximately **___ square feet**.
Now, let's calculate the lengths:
1. **Length of line CD (C(4,0) to D(2,-3))**:
- Using the distance formula: \( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \)
- \( d_{CD} = \sqrt{(2 - 4)^2 + (-3 - 0)^2} = \sqrt{(-2)^2 + (-3)^2} = \sqrt{4 + 9} = \sqrt{13} \)
2. **Length of line AB (A(-4,1) to B(-2,4))**:
- Using the distance formula:
- \( d_{AB} = \sqrt{(-2 - (-4))^2 + (4 - 1)^2} = \sqrt{(2)^2 + (3)^2} = \sqrt{4 + 9} = \sqrt{13} \)
Both lengths are \(\sqrt{13}\).
To find the area of the rectangle:
Area = Length × Width = \( \sqrt{13} \times \sqrt{13} = 13 \) square feet.
So, the completed answer is:
The final answer is approximately **13 square feet**.
