Answer: 20 acres = 80,937.13 m²
'Square acres' is redundant. Just say acres. One square mile has 640 acres. 20 acres is 1/32 of a square mile
one acre is equal to:43560 square feet4840 square yards4046.85 square meters.0015625 square milesmultiply any of these by 78 for your answer
20 acres = 96,800 square yards.
A square with an area of 20 acres has a perimeter of about 3,733.5 feet.
In terms of square footage, 20 acres = 871,200 square feet.
20 acres is 871,200 square feet.
2o acres is 871,200 square feet.
20 acres comprises 871,200 square feet.
As asked, it is impossible to answer as acres are a measure of area (and are a square unit) whereas miles are a measure of length (and a linear unit). However, if you meant: are 100000 acres less than 20 SQUARE miles, then: Convert to the same units, then a comparison can be made: 1 square mile = 640 acres → 20 square miles = 20 x 640 acres = 12,800 acres < 100,000 acres → No, 100,000 acres are not less than 20 square miles.
The question, as stated, cannot be answered sensibly. A square foot is a measure of area, with dimensions [L2]. A metre is a measure of distance, with dimensions [L]. The two measure different things and elementary dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
20 square miles = 12,800 acres.
20 acres is 871,200 square feet.
