  x = 60 ft

Step-by-step explanation:

The area of the old parking lot is ...

  Old Lot Area = Overall Area - School Area

  = (165+75)(300+75) -(165)(300) = 40500 . . . ft^2

The area of the expanded parking lot is ...

  (165 +75 +x)(300 +75 +x) -(165)(300) = x^2 +615x +40500

We want this to be twice the area of the Old Lot, so we want ...

  2·40500 = x^2 +615x +40500

  x^2 +615x -40500 = 0 . . . . put into standard form

  (x +675)(x -60) = 0 . . . . . . . factor

  x = 60 . . . . . . the positive solution

The old parking lot was expanded by 60 feet to make the expanded lot.
