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.
4356 square feet = 66 ft (1 chain) squared = 1/10 acre
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)

The area of Chain of Rocks Park is 120,434.44713062402 square meters.
1 furlong = 10 chains 1 acre = 1 furlong x 1 chain = 1 furlong x 0.1 furlong = 0.1 sq furlong.
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.
