Answer:
2.0417 ft, or 49/24 ft
Step-by-step explanation:
We assume the garden has the shape of a rectangle and has the area 15 3/4 ft^2. Since Area = Width*Length in this case,
Width = Area / Length = 15 3/4 ft / 7 5/7 ft, or
Width = 63/4 ft / 54/7 ft
63 7
Width = ---------- * ----------- ft = 2.0417 ft, or 49/24 ft
4 54
