20x2 = 40 in width
180-40= 140
140/2=70
70 inches
Present area = 120 * 80 = 9600 ft^2 so the new area will be 9600 + 4400 = 14000
So if increase in length = x we have
(x + 120)(x + 80) = 14,000
x^2 + 200x + 9600 - 14000 = 0
x^2 + 200x - 4400 = 0
x = 20 feet answer
If it was one year it would be 2200 and you just keep adding 200 for each year.
