SAM lives in a lot that he thought was a square 157 feet by 157 feet.
when he had it surveyed he discovered that one side was actually 2 feet longer that he thought and the other was actually 2 feet shorter than he thought.
how much less area does he have than he thought he had?
:
Find the area of both
157*157 = 24649
155*159 = 24645
-------------------
difference: 4 sq/ft less
