Let the length of the garden be x ft and the width be y ft.

2 times width = 2y ft.
1 ft less than 2 times width = (2y - 1) ft.
This value is equal to length = x ft.
So, 2y - 1 = x
or 2y = x + 1 ________(1)

Perimeter = 2(Length + Width)
So, 46 = 2(x + y) ________ (2)
Substituting, '2y' from (1) in (2)
46 = 2x + (x + 1)
or 3x = 46 - 1 = 45
or x = 45/3
or x = 15

So, y = (15 + 1)/2 = 8

Thus, length = 15 ft and width = 8 ft.
