Great post.

However, I translate the 5 example and what is wrong with this:

garden : L1 L1 W1 W1

walkway: L2 L2 W2 W2

L1= 2*W2

L1 - W1 = 10

W1= 6

W2 = ?

2W2 - 6 = 10 >>>> W2 = 8

Same of the post above. May a Mod could say something about .......................

I have a problem here.
it is said that: If the problem says ‘the difference of x and y’ it means ‘x – y’
is it true? isn't it means |x-y|, stated i other words, the distance between x and y?

All,

The length of a rectangular garden surrounded by a walkway is twice its width. If difference between the length and width of just the rectangular garden is 10 meters, what will be the width of the walkway if just the garden has width 6 meters?

Note: My translation :"The length of a rectangular garden surrounded by a walkway is twice its width." =>

Let L,W be the length and width of the garden respectively. Let x be the width of the walkway. According to the above statement L = 2x.

" If difference between the length and width of just the rectangular garden is 10 meters"

L - W = 10

also W = 6. => L-6 = 10 => L = 16 => x=8. but the explanation above is still not clear for me.


Please can some one explain how the author translated the above statements in to equation as above?
Thanks,
Vids


I have the same question....could someone please explain this example?


I am unable to understand this problem too. Why do we assume uniform width for walkway?

I tried to understand the derivation of the first author, but failed to do so. So, I just drew a figure. Once you understand that the width of the rectangular garden includes the walkway and that "just the garden" lies within this rectangular, the question becomes simple.
