Answer
$5\text{ ft } 8\text{ in}$
Work Step by Step
Note that $1$ foot = $12$ inches.
Thus,
$14$ ft $4$ inches
$\\= 13$ ft + $1$ ft +$4$ in
$\\=13$ ft + $12$ in + $4$ inc
$\\=13$ ft + $16$ in
Thus, the given subtraction problem is equivalent to:
$=(13\text{ ft } 16\text{ in})-(8\text{ ft } 8\text{ in})
\\=(13-8)\text{ ft} + (16-8)\text{ in}
\\=5\text{ ft} + 8\text{ in}
\\=5\text{ ft } 8\text{ in}$
