Answer:

[tex]w=2\frac{4}{5}~inches[/tex]

Step-by-step explanation:

[tex]A=3\frac{1}{5}=\frac{3*5+1}{5}=\frac{16}{5}\\ \\l=1\frac{1}{7}=\frac{1*7+1}{7}=\frac{8}{7}\\ \\A=w*l=>w=\frac{A}{l}\\ \\=\frac{\frac{16}{5}}{\frac{8}{7}}\\ \\=\frac{16}{5}*\frac{7}{8}\\ \\=\frac{2}{5}*\frac{7}{1}\\ \\=\frac{14}{5}\\ \\=2\frac{4}{5}~inches[/tex]
