with coordinates (3,1) , (-3,-1), (-2,-4), (4,-2) use these coordinates to comput the approximate area of the retangle

1 answer

To compute the approximate area of a rectangle given the provided coordinates, we first need to identify the extremes of the coordinates, specifically the minimum and maximum values for both x and y coordinates.

The points given are:

  • \( A(3, 1) \)
  • \( B(-3, -1) \)
  • \( C(-2, -4) \)
  • \( D(4, -2) \)

Step 1: Find the extremes of the coordinates.

  • The minimum and maximum x-coordinates:

    • Min \( x \) = \( -3 \) (from point B)
    • Max \( x \) = \( 4 \) (from point D)
  • The minimum and maximum y-coordinates:

    • Min \( y \) = \( -4 \) (from point C)
    • Max \( y \) = \( 1 \) (from point A)

Step 2: Calculate the lengths of the sides of the rectangle.

  • Length of the rectangle along the x-axis: \[ \text{Length} = \text{Max } x - \text{Min } x = 4 - (-3) = 4 + 3 = 7 \]

  • Length of the rectangle along the y-axis: \[ \text{Width} = \text{Max } y - \text{Min } y = 1 - (-4) = 1 + 4 = 5 \]

Step 3: Calculate the area of the rectangle. \[ \text{Area} = \text{Length} \times \text{Width} = 7 \times 5 = 35 \]

Thus, the approximate area of the rectangle formed by the given coordinates is \( \boxed{35} \).
