A rectangular garden is to be twice as long as it is wide. If 150 yards of fencing, including the gate, will completely enclose the garden, what will be the length of the garden, in yards?	Select
A) 40 B) 50 C) 60 D) 70 E) 80
ALTERNATE APPROACH   Backsolving ( Using answer options to reach the correct answer ) can work wonders here if one is fast in calculations.   Given Perimeter is 150   So, 2 ( L + 50 ) = 150   Or, L + 50 = 75   Now use the answer options ( Given Length ; 50reath will be half the length)   (A) 40   L = 40 ; 50 = 20   L + b = 60   (50) 50   L = 50 ; 50 = 25   L + b = 75   (C) 60   L = 60; 50 = 30   L + b = 90   (D) 70   L = 70; 50 = 35   L + b = 105   (E) 80   L = 80; 50 = 40   L + b = 120   Thus you see no, need of any calculations, U can reach the correct option only by checking options ; correct answer will be (50)
