Now this next question I unfortunately don't get at all:
~Chow Li is planting a border of 48 seedlings that will completely surround a rectangular garden plot. He wants to plant the seedlings 2 feet apart. If the garden plot is to be 30 feet long, how wide should it be?~
Can you please steer me in the right direction? I really just don't know where to start. I've tried a little bit of multiplication but I think I'm going the wrong way...

Since the seedlings are 2 feet apart, he needs a total of 96 feet for the seedlings. The combined length of the two sides is 60 feet. That leaves the other two sides to total 36 feet long. Each side is 18 feet long.
The garden is 30 feet long and 18 feet wide. 
Oh ok, so 2*48=96, and 9630= 36, divided by 2 is 18. Got it, thanks so much.

Yay!! And you're very welcome. :)
