Problem 97 of 7
Find the missing coordinate in axis-aligned rectangle with vertices (0,0), (x,0), (x,3), (0,3) given perimeter 18.
Using a hint is okay. It just tells the trainer to give you a little more review.

use distance or coordinate differences to solve.
Hidden until you reveal it.
Perimeter condition must determine the missing coordinate or a stated pair of symmetric options.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Write side lengths in terms of the missing coordinate.
2. Set their sum equal to the perimeter.
3. Solve and check geometric constraints or symmetric options.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
