Charlyn walks completely around the boundary of a square whose sides are exactly 5 km long.
From any point on her path she can see exactly 1 km horizontally in all directions.
What is the area of the region consisting of all points Charlyn can see during her walk?
:
This would be the same as having a 1 km border all the way around a 5km square
therefore
(5+2) * (5+2) = 49 sq/km
