Square lot. Sam has a lot that he thought was a square, 200 feet by 200 feet. When he had it surveyed, he discovered that one side was x feet longer than he thought and that the other side was x feet shorter than he thought.
Find a polynomial A(x) that represents the new area.
If x=2 feet then how much less area does he have than he thought he had?
Initial area= 200*200=40,000 feet^2
Present area A(2)=39,996 feet^2
40,000 – 39,996= 4 feet ^2
I need to know if i done this correctly.
