Set 3: \( (4,1),(-4,1),(4,6),(-4,6) \)

Solution

To determine which set of coordinates represents a rectangle with a length of 8 units and a width of 5 units, we need to check the distances between the points in each set. 1. **Set 1: \( (2,4),(-6,4),(2,0),(-6,0) \)** - Length (horizontal distance between \( (2,4) \) and \( (-6,4) \)): \[ |2 - (-6)| = |2 + 6| = 8 \text{ units} \] - Width (vertical distance between \( (2,4) \) and \( (2,0) \)): \[ |4 - 0| = 4 \text{ units} \] - This set does not match the required dimensions. 2. **Set 2: \( (5,0),(-2,0),(5,5),(-2,5) \)** - Length (horizontal distance between \( (5,0) \) and \( (-2,0) \)): \[ |5 - (-2)| = |5 + 2| = 7 \text{ units} \] - Width (vertical distance between \( (5,0) \) and \( (5,5) \)): \[ |0 - 5| = 5 \text{ units} \] - This set does not match the required dimensions. 3. **Set 3: \( (4,1),(-4,1),(4,6),(-4,6) \)** - Length (horizontal distance between \( (4,1) \) and \( (-4,1) \)): \[ |4 - (-4)| = |4 + 4| = 8 \text{ units} \] - Width (vertical distance between \( (4,1) \) and \( (4,6) \)): \[ |1 - 6| = 5 \text{ units} \] - This set matches the required dimensions. 4. **Set 4: \( (3,7),(-3,7),(3,1),(-3,1) \)** - Length (horizontal distance between \( (3,7) \) and \( (-3,7) \)): \[ |3 - (-3)| = |3 + 3| = 6 \text{ units} \] - Width (vertical distance between \( (3,7) \) and \( (3,1) \)): \[ |7 - 1| = 6 \text{ units} \] - This set does not match the required dimensions. Based on the calculations, the only set of coordinates that represents a rectangle with a length of 8 units and a width of 5 units is: **Set 3: \( (4,1),(-4,1),(4,6),(-4,6) \)**.

To find the coordinates of a rectangle, we need to ensure that opposite sides are equal in length. The first option, with coordinates \( (2,4),(-6,4),(2,0),(-6,0) \), shows that the rectangle has a length of 8 units (from -6 to 2 on the x-axis) and a width of 4 units (from 0 to 4 on the y-axis). The second option \( (5,0),(-2,0),(5,5),(-2,5) \) results in a length of 7 units and a width of 5 units. The third option \( (4,1),(-4,1),(4,6),(-4,6) \) gives a errant dimension of 10 units in length. Last but not least, the fourth option fails the rectangle condition due to inconsistent width. Therefore, the first set has both correct length and width! But wait, there's more! When plotting these coordinates, you can visualize these rectangles in the coordinate plane almost like a game of connect-the-dots. The first option will give you a flat rectangle, while the others would yield different-shaped arrangements. Next time you’re trying to create your own designs using math, just remember that achieving the right area isn’t just about the numbers; it's about how you draw it out!
