Step-by-step explanation:
Problem:
The area of a rectangular rug is 81x/3 yd². If the width of the rug is 9x/3 yd, what is the length of the rug?
Solution:
A = LW
\begin{gathered}\begin{array}{l}\frac{{81x}}{3} = (L)(\frac{{9x}}{3})\\\\L = \frac{{\frac{{81x}}{3}}}{{\frac{{9x}}{3}}}\\\\L = \frac{{27}}{3}\\\\L = 9yd\end{array}\end{gathered}
3
81x
=(L)(

)
L=
