side=sqrt%28area%29=sqrt%2848841m%5E2%29=221+m The length of the sides is 221 meters. The area inside the path will be shorter by 6 m (3 m at each end)
So the area inside the path is (215m*215m)=46225 square meters. Total area minus area inside path leaves area of path:
48841M%5E2-46225m%5E2=2616m%5E2 The area of the path is 2616 square meters.
Cost=%28R2%2Fm%5E2%29%282616m%5E2%29=R5232 ANSWER: The path will cost R5232.
