A regular hexagon has a perimeter of $p$ (in length units) and an area of $A$ (in square units). If $A = 3,$ then find the side length of the hexagon.
Area of a hexagon = 6* (1/2) s^2* sqrt (3)/2 where s is the side length
So
3 = 6 * (1/2) * s^2 * sqrt (3) / 2
3 = 3* s^2 * sqrt (3) / 2
s^2 = 2/sqrt (3)
s = sqrt [ 2 / sqrt 3] ≈ 1.075
