Background:
1 chain = 22 yards (approximately 20 metres) or 66 feet.
There are 80 chains in a mile.
Answer:
1 square chain = 22x22 or 484 square yards = 66 x 66 or 4356 square feet.
Interestingly 1 acre = 10 square chains (yes, 10).
So 1 square chain = 0.1 acres.
So basically this is just a quotient rule problem with the chain rule Turn the square root into the 1/2 power and the derivative of the bottom with the chain rule is 1/2(1+x^2)^-1/2 and add on the derivative of the inside, 2x the full derivative is ((1+x^2)(1)-(x)(1/2(1+x^2)^-1/2 +2x))/ 1+x^2 since you square the denominator when you apply the quotient rule.
an acre is 1 chain by 1 furlong. 1 chain = 20.11metres 1 furlong = 201.1metres 20.11 x 201.1 = 4046.8 metres squared. or a square with sides 63.6 metres.
A chain is a very old Linear Measure. 1 chain = 22 yards = 66 feet.
1 is a perfect square. This is because the square of 1 is 1.
Oddly enough, an acre was not defined as a square, but as a rectangle -- for example a long, thin parcel of farmland that would be plowed in long furrows. It is 1/640th of a square mile, or 4840 square yards, or 43560 square feet. The simplest designation uses the obsolete units chain (66 feet) and furlong (660 feet or 10 chains or 1/8 mile). Thus an acre is 1 chain by 1 furlong, or 10 square chains, and may have been established as about a day's plowing for an ox. The 1/640th of a mile can be seen in that there are 80 chains to a mile and 8 furlongs to a mile, a unit still seen in various horse race distances today. The SI unit comparable to the acre is a hectare (10000 m2), which is about 2.47 acres.
1 square chain equates to 484 square yards.
chain = 66 feet. rod = 16.5 feet [1/4 of a chain]. link = 7.92 inches (1/100 of a chain). acre = 10 square chains (10 chains by 1 chain = 660 ft x 66 ft = 43560 sq ft)

There were several versions of measuring chains in history, but the most popular for the last 400 years was the Gunter's chain, measuring 66 feet, having 100 links. The 66-foot measurement has the interesting characteristic that it is the square root of 4356, which is 1/10 of the number of square feet in an acre. Thus, ten square chains is on acre. Obviously, a mile is also composed of 80 chains (5280/66). Many land surveys into the 20th century continued to use chains in the USA, as well as rods, which is exactly 1/4 of a chain.
