i need the picture to figure it out :|

  • ParthKohli
The formula for the perimeter is \(P =2(\rm length + width)\).
ParthKohli
  • ParthKohli
Since the length is \(15\) and the width is \(x\), we have this equation:\[2(15 + x) = 54\]Solve for \(x\).

ok figure it out based on the info parth gave (unless you want me to explain more)
anonymous
  • anonymous
would you like more explanation?
anonymous
  • anonymous
Yes, please.
ParthKohli
  • ParthKohli
OK, so do you know that the perimeter is the sum of ALL sides?
ParthKohli
  • ParthKohli
Notice that opposite sides in a rectangle are equal.|dw:1357571260853:dw|
ParthKohli
  • ParthKohli
So the sum of sides will be \(15 + 15 + x + x\). But it is also given that the sum of all sides (perimeter) is \(54\).
anonymous
  • anonymous
Ok.
ParthKohli
  • ParthKohli
So solve the equation \(15 + 15 + x + x = 54\)?

I have to go study for exams for a few min, so let parth finish =3
anonymous
  • anonymous
You have to figure out what x is, right?
ParthKohli
  • ParthKohli
Yes! =)
anonymous
  • anonymous
OK so you divide 15 right?
anonymous
  • anonymous
I can't get on my study page o_o no don't divide by 15 subtract 15+15 from the perimeter and then divide by 2
anonymous
  • anonymous
that should be your answer
anonymous
  • anonymous
7.2?
anonymous
  • anonymous
no i think you did it wrong let me try
anonymous
  • anonymous
54-30=? then divide ? by 2 to get answer
anonymous
  • anonymous
11
anonymous
  • anonymous
o_o no, sorry but very close
anonymous
  • anonymous
12
anonymous
  • anonymous
yes :D
anonymous
  • anonymous
how did you get 11?
anonymous
  • anonymous
just wondering
anonymous
  • anonymous
22 divided by 2
anonymous
  • anonymous
ok then? whatever i wish you good luck on your hw or whatever it is your doing
