Use The coordinates (-3,-1),(-2,-4),(4,-2) and (3,1) to compute to the approximate area of the rectangle

1 answer

To find the area of a rectangle given the coordinates, we need to identify two opposite corners (vertices) of the rectangle. The area can be calculated using the formula:

\[ \text{Area} = \text{length} \times \text{width} \]

First, let's identify the minimum and maximum x and y values from the given coordinates:

  • Points:
    1. (-3, -1)
    2. (-2, -4)
    3. (4, -2)
    4. (3, 1)

Step 1: Determine the min/max coordinates

  • For x-coordinates, we have:

    • Minimum x = -3 (from point (-3, -1))
    • Maximum x = 4 (from point (4, -2))
  • For y-coordinates, we have:

    • Minimum y = -4 (from point (-2, -4))
    • Maximum y = 1 (from point (3, 1))

Step 2: Calculate the length and width

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

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

Step 3: Calculate the area

Now we can calculate the area of the rectangle: \[ \text{Area} = \text{Length} \times \text{Width} = 7 \times 5 = 35 \]

Therefore, the approximate area of the rectangle formed by the given points is 35 square units.
