Hi,
     *[illustration rectangle.png].
The perimeter of a rectangular garden is 22.5m...The area is 12.5m^2
L + w = 11.25
L = (11.25-w)
A = Lw
(11.25-w)w = 12.5m^2
w^2 - 22.5w + 12.5 = 0
{{{w = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}
the dimensions of the garden: 21.93m by  0.57m
*[invoke quadratic "x", 1,-22.5,12.5]
