transform the acres to miles
[tex]25\longrightarrow\frac{25}{640}=\frac{5}{128}[/tex]the area is 5/128 Miles
where x is the missing measure
if the area formula is
[tex]A=B\times H[/tex]where A=5/128 , B=x and h=1/4
so replace and solve x on miles
[tex]\begin{gathered} \frac{5}{128}=x(\frac{1}{4}) \\ \\ x=\frac{5\times4}{128\times1} \\ \\ x=\frac{5}{32} \end{gathered}[/tex]the missing measure is 5/32 Miles
now transform to yards
we multiply the miles by 1760
so
[tex]\begin{gathered} \frac{5}{32}\times1760 \\ \\ =275 \end{gathered}[/tex]the missing measeure is 275 Yards
