4,800 acres.

Explanation:

Because #640s# is the relationship between #s# square miles and acres, so :

#color(green)(a= 640)#
#color(green)(s=7.5)# square miles.

(*Since Pam owns #color(blue)7.5# square miles, so #color(blue)7.5# becomes #color(red)s .#)

Therefore, we would do:

#color(red)(640*7.5)#

Because when a number is with a variable(#color(purple)(640s#), this means it's #color(purple)640# times the variable. So for this case it would be : (as #color(magenta)7.5# is #color(red)s#)

#color(orange)(640 * s = 640*7.5 = 4800) # acres

So Pam owns #color(blue)(4,800)# acres.
