Problem 95 of 7
The model Area = length * width is incomplete for Length and width represent physical dimensions, so they must be positive. Identify a missing constraint.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
add nonnegative, integer, upper/lower-bound, or context restrictions.
Hidden until you reveal it.
Missing constraint must be necessary from context and absent from model.
Enter your answer
Your answer is equivalent to the expected form.

Full solution stays hidden until you ask for it.
1. Read the context for physical limits, minimums, maximums, and whole-number requirements.
2. State a constraint that the current model omits.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Constraints already present in the model.
