    so it would be 2(2x+4)+2(x+4)=P ?

    What does P equal?

    p=perimeter....so that equation would be correct tho?

    What do you think the 46 is for?

    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.

    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?

    Yes, however, it will be much more easier to solve if you use the first equation you created to solve for x.

    The one you created where you included the P variable.

    i got a=126 but the book says the answer is 50 sq ft...

    Show all of your work actually...For both perimeter and area

    a= (x+4)(2x+4) a= (5+4)(2(5)+4) a=(9)(14) a=126

    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

    Yes, that is correct. Is that your corrected solution?

    the book says the area is 50 sq ft, not 126

    The solution is indeed 50. For next time, you have to read the question more carefully so that you can avoid making such mistakes.

    It asked for the dimensions of the garden, not the fencing

    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?

    But you already calculated the correct area. I don't understand how you're still confused about this.
