Answer:
24 students per mile
Step-by-step explanation:
Given in the question,
Length of rectangle for building university = 75 miles
Width of rectangle for building university = 25 miles
Total area:
Length x Width
= 75 x 25
= 1875 miles²
Only 70% of the buildings at this university are used for instruction
70% of 1875 miles²
70/100 x 1875
= 1312.5 miles²
32,125 students are enrolled at this university
So,
1312.5 miles² = 32,125 students
1 mile = 32,125/1312.5
= 24 students per mile
