20 acres comprises 871,200 square feet.
There are 5280 feet in one mile. Therefore, 20 miles per hour is equal to 20 x 5280 = 105600 feet per hour. Dividing this by 60 minutes in one hour gives 105600 / 60 = 1760 feet per minute.
1 acre = 43,560 square feet = 4,840 square yards-- If the given dimensions are in feet . . . 220' x 440' = 96,800 square feet = 22/9 acres.-- If the given dimensions are in yards . . . 220yd x 440yd = 96,800 square yards = 20 acres.Check: 1/8 mile x 1/4 mile x 640 acres/mile2 = 20 acresyay!
There is no definitive answer for this question. There are actually an infinite number of valid answers, depending completely on the proportions of the 20-acre rectangle.The shortest possible distance around a 20-acre rectangle is 3,733.52 feet; in this case the rectangle is actually a square that is 933.38 feet on a side. Every other possible rectangle would have a longer circumference.ExamplesA rectangle that measures 500 feet by 1,742.4 feet would enclose 20 acres; it would have a circumference of 4,484.8 feet.A rectangle that measures 200 feet by 4,356 feet would enclose 20 acres; it would have a circumference of 9,112 feet.A rectangle that measures 50 feet by 17,424 feet would enclose 20 acres; it would have a circumference of 34,948 feet.As these examples illustrate, the distance around the 20-acre rectangle increases dramatically as the rectangle becomes farther from square. In fact, the upper limit of the circumference would be defined as "approaches infinity" as the short sides of the rectangle approach zero in length.

20 acres=871207 feet
There are 5280 feet in one mile. Therefore, 20 feet is equal to 20/5280 = 0.00378 recurring (that is, 0.003787878...) miles.
20 acres is 871,200 square feet.
There are 5280 feet in a mile, 5280 divided by 20 is 264 feet.
Answer: 20 acres = 871,200 ft²
There are 5280 feet in one mile. Therefore, 105600 feet is equal to 105600 / 5280 = 20 miles.
871,200 square feet
A mile at 5280 feet, is longer than 20 feet. but 20 feet is about 1/264 th of a mile.
871,200
871,200 ft2 equates to 20 acres.
The area described in the question is undefined; "20 acres" is an area itself, not a length.
