that just means area. area is given in terms of square units
anonymous
  • anonymous
i say don't worry about it
anonymous
  • anonymous
you wouldn't say the area of a table top is 10 feet. that is a linear measure. you could say it is 10 square feet
anonymous
  • anonymous
the ^2 pertains the the letters, not the numbers
anonymous
  • anonymous
yeah what ecin said
anonymous
  • anonymous
follow this, Let x be the original side A=169 A=s^2 169=(x+8)^2, we can extract the square root of both sides 13=x+8 x=13-8 x=5 cm , this is the original side
anonymous
  • anonymous
so u would say for 169cm^2 , 169 square feet. so u just squared the 169? then - from 8

satellite wait till she got to volume

cubic units

if you had something that's 16 sq ft and it is square in shape
anonymous
  • anonymous
no, square root of 169 is 13.
anonymous
  • anonymous
then each side would be 4, .. and the area is 4^2
anonymous
  • anonymous
actually i did not square the 169. i thought of a number whose square is 169
anonymous
  • anonymous
sry pat that is what I meant not square feet
anonymous
  • anonymous
in other words \[\sqrt{169}=13\]
anonymous
  • anonymous
yeah, but that is having the same concept
anonymous
  • anonymous
but that's only the case of a truly square shape, for now you should just ignore the sq units and just put it on the answer as a definition
anonymous
  • anonymous
it is okay...
anonymous
  • anonymous
l*w= A * some^2 unit
anonymous
  • anonymous
yeah well i hope to not take anymore math after this class, keeps me stresses grrrr..lol
anonymous
  • anonymous
quit while you are ahead!
anonymous
  • anonymous
a cm * b cm = a* b cm^2, not cm^2 will always be there, so take it as a definition
anonymous
  • anonymous
in my case, i do pay attention because its' not always the same. I'm in engineering
anonymous
  • anonymous
just follow what i did awarr28
anonymous
  • anonymous
oh ok ecin, at least I'm taking notes, but half the time I have to keep coming back to ask because i still cant figure it out...lol
anonymous
  • anonymous
start with basic things, and things you can conceptualize
anonymous
  • anonymous
yes I wrote that down pat, thank you all for all your help
anonymous
  • anonymous
you are welcome^_^
anonymous
  • anonymous
say you have tiled floors and they are all 1 feet
anonymous
  • anonymous
or mess around with the little squares in graph papers think about them as square feets
anonymous
  • anonymous
ok, I thank you all for your help.
anonymous
  • anonymous
1 feet by 2 feet = 2 squares
anonymous
  • anonymous
its like you are shading every little box or tile you count
anonymous
  • anonymous
oh ok I see what your saying
anonymous
  • anonymous
2 feet by 3 feet are six boxes
anonymous
  • anonymous
and that's the area
anonymous
  • anonymous
dont' worry about why, but just put it at the end ft^2
anonymous
  • anonymous
so 2 feet by 6 feet would be 12 boxes right?
anonymous
  • anonymous
yea
anonymous
  • anonymous
;)
anonymous
  • anonymous
you can also think about it like this "clear the area"
anonymous
  • anonymous
you don't want nothing or nobody in that space
anonymous
  • anonymous
a perimiter on the other hand is just like a gate.. is a measurement of the outside
anonymous
  • anonymous
gotcha
