work out the missing length x

Answer:
[tex]x = 12m[/tex]
Step-by-step explanation:
[tex]area = length \: \times breath[/tex]
[tex]length = \frac{11}{3} m[/tex]
[tex]breath \: = x \\ since \: area = 44 \\ 44 = \frac{11}{3} \times x \\ cross \: multiply \\ 44 \times 3 = 11x \\ 132 = 11x \\ divide \: both \: sides \: by \: \\ \frac{132}{11} = \frac{11x}{11} \\ 12m = x[/tex]
