A middle school campus is shaped like a rectangle with a width of 1/4 mile and a length of 1/2 mile. A map of the campus has a width of 1/2 foot and a length of 1 foot. What is the ratio of the area in square miles of the campus to the area in square feet of the map? A) 1:4 B) 1:2 C) 2:1 D) 4:1

A) 1:4

Step-by-step explanation:

#We first calculate the campus' area:

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

Ratio is a comparison between two dimensions:

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

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
