To find the perimeter of the rectangle with vertices at (0, 0), (4, 4), (5, 3), and (1, -1), we first need to confirm whether these points indeed form a rectangle and then calculate the lengths of two adjacent sides.
Step 1: Determine the vertices
We have the vertices:
- A(0, 0)
- B(4, 4)
- C(5, 3)
- D(1, -1)
Step 2: Calculate the lengths of the sides
Length of AB:
Using the distance formula: \[ AB = \sqrt{(4-0)^2 + (4-0)^2} = \sqrt{16 + 16} = \sqrt{32} = 4\sqrt{2} \approx 5.7 \]
Length of BC:
\[ BC = \sqrt{(5-4)^2 + (3-4)^2} = \sqrt{1 + 1} = \sqrt{2} \approx 1.4 \]
Step 3: Calculate the perimeter
The perimeter (P) of a rectangle is given by: \[ P = 2 \times (length + width) \] Assuming AB as one side (length) and BC as the other (width): \[ P = 2 \times (AB + BC) \approx 2 \times (5.7 + 1.4) \]
Calculating the sum: \[ 5.7 + 1.4 = 7.1 \]
Calculating the perimeter: \[ P \approx 2 \times 7.1 = 14.2 \]
Final rounded answer
Thus, the perimeter of the rectangle is approximately 14.2 units.
