To find the area of the rectangle using the given coordinates, we need to identify the vertices of the rectangle and calculate the lengths of its sides.

The coordinates provided are:
- A: (-5, 6)
- B: (-2, 6)
- C: (-1, 1)
- D: (-5, 1)

**Step 1: Identify the vertices of the rectangle.**

From the coordinates, we can see that:
- Vertices A and B have the same y-coordinate (6), indicating they are along the top side of the rectangle.
- Vertices C and D have the same y-coordinate (1), indicating they are along the bottom side.
- The x-coordinates of A and D are both -5, while the x-coordinates of B and C are different.

**Step 2: Calculate the length and width of the rectangle.**

- **Length (horizontal distance between A and B):**
\[
|x_B - x_A| = |-2 - (-5)| = |-2 + 5| = 3 \text{ units}
\]

- **Width (vertical distance between A and D):**
\[
|y_A - y_D| = |6 - 1| = 5 \text{ units}
\]

**Step 3: Calculate the area of the rectangle.**

The area \(A\) of a rectangle is given by:
\[
A = \text{Length} \times \text{Width}
\]
Substituting the values we found:
\[
A = 3 \text{ units} \times 5 \text{ units} = 15 \text{ units}^2
\]

Thus, the area of the rectangle is **15 units²**.

The correct response from the options provided is **15 units²** or **15 units squared**.

My bad, C's coordinates are (-2, 1)

No problem! Let's recalculate the area of the rectangle with the updated coordinates for C.

The revised coordinates are:
- A: (-5, 6)
- B: (-2, 6)
- C: (-2, 1)
- D: (-5, 1)

**Step 1: Identify the vertices of the rectangle.**

- Vertices A and B (top side of the rectangle) have the same y-coordinate (6).
- Vertices C and D (bottom side of the rectangle) have the same y-coordinate (1).
- The x-coordinates of A and D are both -5, while the x-coordinates of B and C are both -2.

**Step 2: Calculate the length and width of the rectangle.**

- **Length (horizontal distance between A and B):**
\[
|x_B - x_A| = |-2 - (-5)| = |-2 + 5| = 3 \text{ units}
\]

- **Width (vertical distance between A and D, or between C and B):**
\[
|y_A - y_D| = |6 - 1| = 5 \text{ units}
\]

**Step 3: Calculate the area of the rectangle.**

The area \(A\) of a rectangle is given by:
\[
A = \text{Length} \times \text{Width}
\]
Substituting the values we found:
\[
A = 3 \text{ units} \times 5 \text{ units} = 15 \text{ units}^2
\]

So, the area of the rectangle is still **15 units²**.

The correct response from your options is **15 units²** or **15 units squared**.
