Question

Suppose a rectangle is drawn on a coordinate plane. What is the perimeter of the rectangle if its vertices are at coordinates (0, 0). (4, 4), (5, 3), and (1, -1)? Round your answer to the nearest tenth. (1 point)
The perimeter is approximately ____units.

Answer 1

To find the perimeter of the rectangle given the vertices at (0, 0), (4, 4), (5, 3), and (1, -1), we first need to verify that these points indeed form a rectangle.

1. **Check Distances Between Points**:
- Calculate the distance between each pair of points.

Using the distance formula \( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \):

- Distance between (0, 0) and (4, 4):
\[
d = \sqrt{(4 - 0)^2 + (4 - 0)^2} = \sqrt{16 + 16} = \sqrt{32} \approx 5.7
\]

- Distance between (0, 0) and (1, -1):
\[
d = \sqrt{(1 - 0)^2 + (-1 - 0)^2} = \sqrt{1 + 1} = \sqrt{2} \approx 1.4
\]

- Distance between (4, 4) and (5, 3):
\[
d = \sqrt{(5 - 4)^2 + (3 - 4)^2} = \sqrt{1 + 1} = \sqrt{2} \approx 1.4
\]

- Distance between (5, 3) and (1, -1):
\[
d = \sqrt{(1 - 5)^2 + (-1 - 3)^2} = \sqrt{16 + 16} = \sqrt{32} \approx 5.7
\]

- Distance between (1, -1) and (4, 4):
\[
d = \sqrt{(4 - 1)^2 + (4 - (-1))^2} = \sqrt{9 + 25} = \sqrt{34} \approx 5.8
\]

- Distance between (4, 4) and (1, -1):
\[
d = \sqrt{(1 - 4)^2 + (-1 - 4)^2} = \sqrt{9 + 25} = \sqrt{34} \approx 5.8
\]

2. **Confirming Rectangle Properties**:
From these calculations, it does not appear that these points form a rectangle, as the opposite sides don’t equal and the angles are not right angles.

3. **To Calculate Perimeter**:
To further confirm, we will sum up the distance of each adjacent pair to utilize for the perimeter formula \( P = 2(l + w) \), where \( l \) is length and \( w \) is width.

If we incorrectly assumed it to be a rectangle, following the distances calculated would yield us:
- Lengths found (assuming opposite sides were paired correctly) yield no successful rectangle fit.

Thus, with the uncertainty if any rectangle could occur through diagonal vertices, the perimeter can't be calculated directly via generic rectangle formulae.

After re-evaluating per pairs inconclusively returning non-rectangle sides/all relationships incorrect for rectangle, we conclude:

The approximate perimeter can't be strictly derived as such through vertex set based as approximations exceed segments forming fewer equal sides.

**Conclusion**: To represent the complexities explored and confirming adjacency. Provide clarity:
Since edges do not yield a rectangle, alternative approaches might be warranted i.e pairs on cartesian not maintaining rectangle symmetry expected.

**Final statement**: The figure does not appropriately represent a rectangle; thus no perimeter can be generalized for given non-rectangular points.
