1998 CEMC Gauss (Grade 7) Problems/Problem 7
A rectangular field is 80 m long and 60 m wide. If fence posts are placed at the corners and are 10 m apart along the 4 sides of the field, how many posts are needed to completely fence the field?
There is one post on each of the corners.
There are 7 posts along each of the two lengths and 5 posts along each of the two widths.
In total, this gives us posts.
