    The length of a rectangular picture frame has been found to be an irrational number. Dwayne says that because the length is an irrational number, the perimeter and area would always be irrational. Using complete sentences, critique Dwayne’s statement with examples that demonstrate how he is correct or incorrect.

    he is wrong. suppose length is √(2) and width is 2√(2). Area would be 4, and 4 is a rational number.

    yes, you gave one correct counter example. perimeter = 2 (l+w) will always be irrational since l is irrational Area A = l*w can become rational

    we both are saying the same thing, that dwayne is incorrect and Trojan gave a correct example to prove it :)
