The formula to find the area of a parallelogram is given as
[tex]a=b\times h[/tex]
where
a = area
b = base length
h = perpendicular height
From the question, we have the following values:
a = 744 mi²
b = z
h = 24 mi
Substituting into the equation, we have
[tex]744=z\times24[/tex]
Solving for z, we have
[tex]\begin{gathered} z=\frac{744}{24} \\ z=31\text{ mi} \end{gathered}[/tex]
Therefore, the answer is 31 miles.
