Step 1 :Convert the width of the garden to centimeters: \(3.5 \mathrm{~m} \times 100 = 350 \mathrm{~cm}\)
Step 2 :Divide the width of the garden in centimeters by the length of the boot: \(\frac{350 \mathrm{~cm}}{32 \mathrm{~cm}} = 10.9375\)
Step 3 :\(\boxed{10.94}\) boot lengths is the approximate width of the garden
