Roses were planted 100 cm apart around a rectangular garden. There were no roses at the corners. They started 1 m from each corner. The garden was 5 m by 3 m. How many roses were planted?

math 
Steve,
For a side of n meters, n2 meters have roses, so there are 10(n2)+1 roses.
total roses: 2(10(52)+1 + 10(31)+1) = 104
