let us represent the area as A and perimeter as P.
A=LW 
A=230m²
P=2L+2W
P=66m
Let us make an equation to find L using the perimeter. 
P=2L+2W
66=2L+2W.. transpose 66 to the other side
-2L=2W-66.. divide both sides by -2
L=-W+33.. then we substitute this to the A=LW
A=-W+33(W)
230=-W²+33W
W²-33W+230=0..let us get the roots.
(W-23)(W-10)
W=23, W=10.. the dimensions are L=23, W=10
