Answer by ptaylor(2198) (Show Source): You can put this solution on YOUR website!
Let x=width of parking lot
Then x+3=length of parking lot
Area of rectangle equals Length times Width. So our equation to solve is:
get rid of parens
subtract 180 from both sides
quadratic in standard form
A=1
B=3
C=-180
We will solve using the quadratic formula:

-------------------------discount the negative value for length
-------------------------width of field
---------------------------length of field

15*12=180
180=180
also 15 is 3 more than 12
