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: $=(13\text{ ft } 16\text{ in})-(8\text{ ft } 8\text{ in}) \\=(13-8)\text{ ft} + (16-8)\text{ in} \\=5\text{ ft} + 8\text{ in} \\=5\text{ ft } 8\text{ in}$
