With the given information, no one can say for certain whether or not the window is other than a rectangle. What can be said for certain is that at least one part of what the salesman said is wrong. If everything that the salesman said were true, then putting the given values into the Pythagorean Theorem would result in a true statement. Since such a substitution does not, in fact, create a true statement, all you can say for certain is that the salesman presented 4 pieces of information as if they were facts and that either 1, 2, 3, or all 4 of such pieces of information are wrong. Even if you read the problem such that the length and width can be accepted as true measurements, you still will have doubt as to whether the measure of the diagonal or the claim of rectangularity is the actual error commited by the salesman.
