My shadow would be 7 feet tall.
Since I am standing next to the fence, then whatever difference its actual height and its shadow has, will be the same difference of my shadow to my actual height.
fence: Actual height - 4 ft ; Shadow height - 5 ft; difference - 1 ft
me : Actual height - 6 ft : Shadow height - ? ; difference - 1ft
Shadow Height - Actual Height = 1 ft
Sh - 6ft = 1ft
Sh = 1ft + 6ft
Sh = 7ft
