|dw:1328999809861:dw| Can you figure it out from here?

so it would be 2(2x+4)+2(x+4)=P ?
Hero
  • Hero
What does P equal?

p=perimeter....so that equation would be correct tho?
Hero
  • Hero
What do you think the 46 is for?
anonymous
  • anonymous
ahhh i wasn't sure...
anonymous
  • anonymous
There are 46 feet of fence, so P=46.

Mertsj, when you see me helping a student, I don't think you should interfere like that. You're the only person here that does that and I don't appreciate it. I will be discussing this with the mods. I've asked you countless times to respect my wishes, but you continue to ignore me.

  • anonymous
you are my hero, hero! i appreciate that you didnt give me the final answer so that i could try and figure it out myself
Hero
  • Hero
Okay, not to worry. I will discuss this issue with the mods and hopefully get a resolution we can all agree with. The only problem is, mertsj seems to not want to communicate with me, which makes the matter much more difficult. I will be directing the mods and administrators to this chat. Thanks for providing your feedback regarding this. That helps a lot.

ok, so part b of this problem is finding the area of the garden. if the area is the length times the width would the equation be a=(x+4)(2x +4) and would a=46 squared?
Hero
  • Hero
Yes, however, it will be much more easier to solve if you use the first equation you created to solve for x.
Hero
  • Hero
The one you created where you included the P variable.
anonymous
  • anonymous
oh so just plug in 5 for x?
Hero
  • Hero
Precisely :)

i got a=126 but the book says the answer is 50 sq ft...
Hero
  • Hero
So me the work you did to find the area
Hero
  • Hero
Show all of your work actually...For both perimeter and area
anonymous
  • anonymous
a= (x+4)(2x+4) a= (5+4)(2(5)+4) a=(9)(14) a=126
anonymous
  • anonymous
p=2(x+4)+2(2x+4)=46 2x+8+4x+8=46 6x+16=46\ 6x=30 x=5; 2x=10 5 by 10
Hero
  • Hero
Yes, that is correct. Is that your corrected solution?
anonymous
  • anonymous
the book says the area is 50 sq ft, not 126
Hero
  • Hero
The solution is indeed 50. For next time, you have to read the question more carefully so that you can avoid making such mistakes.
anonymous
  • anonymous
ohhhhh so the inside then not the fencing....
Hero
  • Hero
Read the original question again
Hero
  • Hero
It asked for the dimensions of the garden, not the fencing
Hero
  • Hero
But you know that now...
Hero
  • Hero
So great job
anonymous
  • anonymous
haha ok so a gardener has 46 ft of fencing to be used to enclose a rectangular garden that has a border of 2 ft wide surrounding it. so the area of that would be a=2x?
anonymous
  • anonymous
are you there?
Hero
  • Hero
But you already calculated the correct area. I don't understand how you're still confused about this.
