1. rachel/411

is it A?

2. rachel/411

@AriPotta

3. AriPotta

quadrupled. do you remember what i said on the perimeter question by accident? that applies to this :)

4. rachel/411

oooh lol

5. rachel/411

duh. it says 'area' lol

6. AriPotta

yep, and since it's doubled, it would 2^2, or 4 times the original area

7. rachel/411

i get it thanks for the thousandth time lol

8. AriPotta

would be*

13. AriPotta

36/9 =

14. AriPotta

4

15. rachel/411

yesh

16. rachel/411

so anytime its area its quadrupuled?

17. AriPotta

no. anytime the dimensions are doubled, the area is quadrupled

18. AriPotta

2^2

19. rachel/411

ooh. mk

20. AriPotta

if the dimensions were tripled, the area would be 9 times the original area. 3^2

21. rachel/411

mk. tnx:)

22. AriPotta

and for volume, you would cube it

23. rachel/411

^2 every time?

24. AriPotta

if the dimensions were doubled, the volume would be 2^3 or 8 times the original

25. rachel/411

mhmm. mk.thanks:)
