 Question from Kerry: If you have a perfect square that is one quarter of an acre what are the length of the sides and how do you arrive at the solution?thank you, Kerry.

Hi Kerry,

There are 43560 square feet in an acre so one quarter of an acre is $\large \frac{43560}{4} \normalsize = 10890$ square feet. If each side of the square is $F$ feet long then the area is $F^2$ square feet. Thus $F^2 = 10890$ and $F = \sqrt{10890} = 104.35$ feet.
