Answer:
5440 acres
Step-by-step explanation:
Given: The equation a = 640s gives the relationship between s square miles and a acres. Kevin owns 8.5 square miles of farmland.
To Find: How many acres does he own.
Solution:
Area of farmland owned by kevin [tex]=8.5[/tex] [tex]\text{square miles}[/tex]
The given equation is
[tex]\text{a}=640\text{s}[/tex]
here [tex]\text{a}[/tex] is area in acres, and [tex]\text{s}[/tex] is area in square miles.
putting values in equation
[tex]\text{a}=640\times\text{area in sq. miles}[/tex]
[tex]\text{a}=640\times8.5[/tex]
[tex]\text{a}=5440[/tex]
[tex]=5440[/tex] [tex]\text{acres}[/tex]
Hence kevin owns [tex]5440[/tex] [tex]\text{acres}[/tex] of farmland
