Ok, so area/width=length

then they gave you mixed fractions
they want you to practice converting mixed fractions into improper fractions and dividing them

rmember, improper fractions are a/b where a>b sometimes

and also remember that $\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{ad}{bc}$

okie dokie

width
4 and 1/2=width
4+1/2=width
8/2+1/2=width
9/2=width

area=36 and 3/4
area=36+3/4
area=144/4+3/4
area=147/4

so area/width=length
$\frac{\frac{147}{4}}{\frac{9}{2}}=length$
$\frac{(147)(2)}{(4)(9)}=length$
$\frac{294}{36}=length$
$\frac{49}{6}=length$
$\frac{48}{6}+\frac{1}{6}=length$
$8+\frac{1}{6}=length$

so the length is $8 \space\ and \space\ \frac{1}{6} \space\ in$
