x%5E2, the area of the whole plot

x%5E2-60%2A40, the area of just the parking lot

x%5E2-2400=12000, parking lot area was given.

The plot of land is square with side length x; the plot consists of a 60x40 foot building and a parking lot of 12,000 square feet:

x%5E2=%2860%29%2840%29%2B12000=2400%2B12000=14400
x=sqrt%2814400%29=120

ANSWER: the plot of land is 120 feet by 120 feet.
