To determine the coordinates of the rectangle given points A, B, and C, let's start by identifying the locations of points A, B, and C.

  1. Coordinates of the points:
    • A = (-3, -1)
    • B = (-3, 0)
    • C = (3, 4)

Next, we will find the coordinates of point D, which completes the rectangle.

  1. Finding the fourth point (D):

    • Since A and B have the same x-coordinate, they form a vertical side of the rectangle.
    • C is the diagonally opposite point from A, and thus point D can be determined using the x-coordinate of C and the y-coordinate of B for D.

    Therefore, D should have the coordinates:

    • D = (3, -1)
  2. Coordinates of the rectangle's corners:

    • A (-3, -1)
    • B (-3, 0)
    • C (3, 4)
    • D (3, -1)
  3. Calculating the lengths of sides:

    • The length of AB = distance between A and B (vertical side): \[ |y_B - y_A| = |0 - (-1)| = 1 \text{ unit} \]
    • The length of AD = distance between A and D (horizontal side): \[ |x_D - x_A| = |3 - (-3)| = 6 \text{ units} \]
  4. Compute the area of the rectangle:

    • Area = length × width \[ \text{Area} = 1 , \text{unit} \times 6 , \text{units} = 6 , \text{units}^2 \]

However, I made a mistake on the calculation of the lengths of sides. Let's compute the right dimensions instead.

  • Length of side AB is indeed 1 unit.
  • Length of side BC can be calculated:
    • For side BC, the vertical distance between the y-coordinates of B and C is:
      • \( |y_C - y_B| = |4 - 0| = 4 \text{ units} \)

Therefore, the rectangle's dimensions are correctly identified as follows:

  • Width = AC = 6 units
  • Height = 4 units

Thus, the area: \[ \text{Area} = 6 , \text{units} \times 4 , \text{units} = 24 , \text{units}^2 \]

After reviewing all properties of the points given, NONE of the responses for possible areas match our calculations. Hence, the area of our rectangle formed by points A, B, and C is indeed: \[ \text{Area} = 24 \text{ square units} \]
