SOLUTION

A rectangular garden is to be twice as long as it is wide. If 360 yards of fencing, including the gate, will completely enclose the garden, what will be the length of the garden, in yards?

(A) 120
(B) 140
(C) 160
(D) 180
(E) 200

Say the width and the length of the garden are \(x\) and \(2x\), respectively.

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.

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.
