Thus, \(perimeter=2(x+2x)=360\) > \(6x=360\) > \(2x=length=120\). Answer: A.

We know:
2W + 2L = Perimeter of the rect. garden
We know:
"A rectangular garden is to be twice as long as it is wide." , So.: 2W = L
Putting this Information in our Equation:
6W = Perimeter. Perimteter = 360 Yards, so W = 60.
2*60 = 120
L = 120 Yards.

Thus, \(perimeter=2(x+2x)=360\) > \(6x=360\) > \(2x=length=120\).
Answer: A. How do we decipher that 360 is perimeter and not area? can someone please help. Thanks. 360 yards of fencing completely encloses the garden, so 360 is the length of the fencing. Also, we have units not square units, so it cannot be area. Hope it's clear.

" Is there some difference between"the lengthen is twice as long as the width" and "twice as long as it is wide"? No, both mean the same. Say if the length is 2, then the width is 1: garden is twice as long as it is wide (the length is twice as long as the width).

(A) 120 (B) 140 (C) 160 (D) 180 (E) 200] We first draw a diagram of our garden. The length of the rectangular garden is twice as long is it is wide. Thus, we know: length = 2(width) Thus, we can label length as 2w, where w = width. Let’s plug these values into the diagram. We are given that 360 yards of fencing will completely enclose the garden; thus, the perimeter of the garden is 360 yards. The formula for the perimeter of a rectangle is: perimeter = 2(length) + 2(width) Knowing that length = 2w, width = w, and perimeter = 360 we can plug all this info into our perimeter equation: 360 = 2(2w) + 2w 360 = 4w + 2w 360 = 6w 60 = w Since the width of the garden is 60 yards, the length is 2 x 60 = 120 yards. Answer: A

Hi All, This question can be solved by TESTing THE ANSWERS. We're told that we're dealing with a rectangular garden that has a perimeter of 360 yards of fencing. This means that.... 2(length) + 2(width) = 360 length + width = 180 We're also told that the length is TWICE the width. We're asked for the length of the garden. Since the answer choices are all numbers, it shouldn't take too much arithmetic to figure out which one fits all of the given information. Let's TEST Answer B: 140 yards IF the length is 140 yards, then... 180  140 = 40 140 = TWICE 70 40 does NOT = 70, so this cannot be the answer. To 'shrink' the difference in the two values, we'll need a shorter length, and there's only one answer that fits THAT description. You can prove that it's correct with just a little more work though... Let's TEST Answer A: 120 yards IF the length is 140 yards, then... 180  120 = 60 120 = TWICE 60 60 DOES = 60, so this MUST be the answer. Final Answer: GMAT assassins aren't born, they're made, Rich
