Hi pooja.

Uh i think the answer is in the question....if im right

divide it in two first

|dw:1442028600183:dw|

Omg I forgot the shapes have the "fill" option.... anyway.

yeah

When you say divide two first, do you mean 68 ÷ 2 and 6÷ 2

no 68 by 2

then subtract 6 from that

okay, that is 34...

So the Perimeter of a rectangle is represented as: \[\sf P = 2L +2W\]

But we also know something else, \(\sf W=L-6\)

68 - 6?

So we can substitute this in to the formula for the perimeter. \[\sf 68 = 2L+2(L-6)\]

Are you following, @gabbyalicorn ?

Um, somewhat... I don't really get it but i'm following the steps if that's what you mean. :)

Which part are you confused with? Let's clarify that before moving on.

is L the variable we are trying to find

the number for...

but what is L

That is where we use the equation for the perimeter of the rectangle. \(\sf P = 2L +2w\)

Do you see how this works?

I think I'm getting it...

|dw:1442029733818:dw|

Good

:)

\[\sf 68 = 2L +2L-12\]We add +12 to both sides of the equation.

why - 12 I thought you said add

80

So now we have \[\sf 80 = 2L + 2L\]\[\sf 2L + 2L =~?\]

4L ?

Good.

:}

20

Sorry, typo. \(\sf W=L-6\)*

20 - 6 = 14?

That's correct :)

Yes. :)

Great! You worked it out yourself :)

:D Thank you for helping me and not giving up on me! I reallu appreciate it. :)

No problem ^^
