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.

2. Trojan

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

3. Baseballa101

Ok

4. Trojan

@hartnn Is that right? ^

5. hartnn

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

6. Trojan

@hartnn Counter example?

7. Baseballa101

So are you both right?? Who is right??

8. hartnn

yes, an example showing Dwayne is incorrect.

9. Trojan

Oh okay. @hartnn So are we both correct?

10. hartnn

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

11. hartnn

yes, we both are correct

Ok, thank you for helping me out with that
