Answer:

A) 1:4

Step-by-step explanation:

#We first calculate the campus' area:

[tex]a=lw\\\\=\frac{1}{4}\times \frac{1}{2}\\=0.125 \ mi^2[/tex]

#We then calculate the campus' map area in square ft:

[tex]A=lw\\\\=0.5 \times 1\\\\=0.5 ft^2[/tex]

Ratio is a comparison between two dimensions:

[tex]Ratio=\frac{0.125}{0.5}\\\\=0.25\\\\=\frac{1}{4}\\\\=1:4[/tex]

Hence, the ratio of the area in square miles of the campus to the area in square feet of the map is 1:4
