Answer
$l=0.5x^2-0.4x+0.3$
Work Step by Step
The Area of the rectangle is, $A=l \times w$, whereas $l$ is a length of the rectangle and $w$ is the width of the rectangle.
To find the the length $l$, we can divide both sides of the formula by $w$.
$A/w=l$.
Therefore,
$\begin{array}{lllll}
\underline{-0.2}| & 0.5 & -0.3 & 0.22 & 0.06\\
& & -0.1 & 0.08 & -0.06\\
\hline & & & & \\
& 0.5 & -0.4 & 0.3 & 0
\end{array}$
$(0.5x^{3}-0.3x^2+0.22x+0.6)\div(x+0.2)=0.5x^2-0.4x+0.3$.
There by dividing the area by width we can get the length.
$l=0.5x^2-0.4x+0.3$
