he area of the pool is 34 ft * 48 ft = <<34*48=1632>>1632 ft2.
Thus, the total area of the pool and the border strip is 1632 ft2 + 344 ft2 = <<1632+344=1976>>1976 ft2.
Hence, the border strip is 1976 ft2/34 ft = <<1976/34=58>>58 ft long.
Therefore, the border strip can be 58 ft/2 = <<58/2=29>>29 ft wide. Answer: {29}.
