L = ( \frac{2}{3} )w
a = 12 
Length times width = area 
L · w = a
( \frac{2}{3} )w · w = 12
( \frac{2}{3} ) w^{2} = 12
Divide both sides by \frac{2}{3} or mulitply both sides by \frac{3}{2} (either one is fine)
( \frac{2}{3} ) ÷ ( \frac{2}{3} ) w^{2} = 12 ÷ ( \frac{2}{3} )
or
( \frac{3}{2} ) ( \frac{2}{3} ) w^{2} = 12 ( \frac{3}{2} )
w^{2} = 18
Square root both sides to get rid of the squared on the w
\sqrt{w^{2} } = \sqrt{18}
w = 4.24
