DddFor this case we have to know the following conversions:
 1 mile = 1760 yards
 1 foot = 12 inches
 1 acre = 4840 yd ^ 2
 1 yard = 36 inches
 1 yard = 3 feet
 1 acre = 43560 ft ^ 2
 Applying conversions we have:

 13 miles to yards:
 
(13) * (1760) = 22880 yards

 67 square feet to square inches:
 (67) * (12) ^ 2 = 9648 in ^ 2

 4,800 inches to feet:
 
(4800) * (1/12) = 400 feet

 87,120 square yards to acres:
 
(87120) * (1/4840) = 18 acres

 3 miles to yards:
 
(3) * (1760) = 5280 yards

 54 inches to yards:
 
(54) * (1/36) = 1.5 yards

 12 yards to feet:
 
(12) * (3) = 36 feet

 7 acres to square feet:
 
(7) * (43560) = 304920 feet ^ 2
