length = \(l\)
width = w = \(\frac{2}{3}\cdotl\)

\(l\cdot\frac{2}{3}l = 864\)

\(\frac{2}{3}l^2 = 864\)

\(l^2 = 864\cdot\frac{3}{2}\)

\(l^2 = 1296\)

\(\boxed{l=36}\)

\(w=\frac{2}{3}\cdot36\)

\(\boxed{w=24}\)


\(\frac{2}{3}x*x= \frac{2}{3} x^{2}\)

\(\frac{2}{3} x^{2} =864\)

\(x^{2} = 1296\)

\(x=36\)

\(\frac{2}{3}(36)=24\)

\(Length=36\)
\(Width=24\)
