I am looking for how many square metres/feet an area measurement of a cent is.
I have seen some references to a 25 cent plot of land. Looked at the online

Get out your vernier or digital calipers and measure the diameter of the coin; measure several and derive a mean
measurement. A = Pi (3.1416) X R(radius)2(squared)
Area equals Pi times the square of the radius.
or its the going rate for an acre of farmland in dollars ($1000) divided by
.25
or the equation:
x/43560=.25/1000
solve for x
.25X43560=1000x
1742.4=1000x
x=1.7424
@ $1000/acre, $.25 equals 1.7424 square feet
or derive the area of a one cent coin in square feet, multiply it by 25 and
divide that
by 43560 to find what percentage of an acre that is
