( x + 14) ft

Step-by-step explanation:

$length \: of \: rectangle = \frac{area \: of \: rectangle}{width \: of \: rectangle} \\ \\ = \frac{ {x}^{2} + 17x + 42}{x + 3} \\ \\ = \frac{ {x}^{2} + 14x + 3x + 42}{x + 3} \\ \\ = \frac{ x({x} + 14) + 3(x + 14)}{x + 3} \\ \\ = \frac{ ({x} + 14) (x+ 3)}{x + 3} \\ \\ = x + 14 \\ \therefore \: length \: of \: rectangle =( x + 14) \: ft$
