width=3m

length=9m

Step-by-step explanation:

-Let w be the width of the garden.

-Given that the length is 6 units more than the width, l=w+6

-We apply the area formula to solve for w:

$A=lw\\\\27=w(w+6)\\\\w^2+6w-27=0\\\\\#Apply \ Complete \ Squares\\\\w^2-3w+9w-27=0\\\\w(w-3)+9(w-3)=0\\\\(w-3)(w+9)=0\\\\w=3 \ \ \or w=-9\\\\\therefore w=3m\\\\l=w+6=3+6=9m$
