Detailed Solution & Explanation

Start at O(0,0)\displaystyle O(0, 0).
1. North 2\displaystyle 2 km →(0,2)\displaystyle \rightarrow (0, 2).
2. East 10\displaystyle 10 km →(10,2)\displaystyle \rightarrow (10, 2).
3. North 3\displaystyle 3 km →(10,5)\displaystyle \rightarrow (10, 5).
4. East 2\displaystyle 2 km →(12,5)\displaystyle \rightarrow (12, 5).
