## some.random.cool.kid one year ago I need help with some serious math!

1. some.random.cool.kid

The length of each side of a square is square root of seven end square root. What are the exact values of the area and perimeter? Classify each as either rational or irrational.

is $$\sqrt{7}$$ rational or irrational?|dw:1442333625575:dw|

6. some.random.cool.kid

irrational

7. anonymous

okay and what is the perimeter of the square?

8. some.random.cool.kid

7

9. anonymous

no, perimeter is the distance around the square.

10. some.random.cool.kid

49

11. some.random.cool.kid

well wait

12. some.random.cool.kid

28

13. anonymous

how long is one side of the square?

14. some.random.cool.kid

it says one side is worth 7 x 4 sides

15. anonymous

is the picture i drew correct?

16. some.random.cool.kid

would i put 4^sqrt7

17. some.random.cool.kid

uh

18. some.random.cool.kid

look at my attached file

19. some.random.cool.kid

i think its different a little bit.

20. anonymous

is the length of a side $$\sqrt{7}$$?

21. some.random.cool.kid

yes thats what its saying i suppose.

22. anonymous

yes. and how many sides to a square?

23. some.random.cool.kid

its saying the sqrt is 7 times 4 sides being 4^sqrt of 7

24. some.random.cool.kid

or wait no

25. anonymous

4*sqrt(7) = $$4\sqrt{7}$$

26. some.random.cool.kid

its just regular size 4 time sqrt of 7 not power

27. some.random.cool.kid

i read it wwrong.

28. anonymous

$$=\sqrt{7}+\sqrt{7}+\sqrt{7}+\sqrt{7}$$

29. anonymous

and what is the area of a square?

30. some.random.cool.kid

it said the area was 7... but does this make it rational for the area part of it

31. anonymous

is 7 a rational number?

32. some.random.cool.kid

ik the second part is irrational but the first it says rational i was confused.

33. anonymous

A = 7 -> rational P = $$4\sqrt{7}$$ -> irrational

34. some.random.cool.kid

so i was right alright cool :D thank you

35. some.random.cool.kid

but do you have more time to spare?

36. some.random.cool.kid

I need help with a few more not sure if your up to it though but if you have time t spare it would be quite nice @pgpilot326
