The correct option is
A (3,10)
Measuring the distance from the entrance to painting 1 along the grid, we find:
Distance from entrance to painting 1
= 2 units + 8 units
= 10 units
Measuring the distance from the entrance to painting 2 along the grid, we find:
Distance from entrance to painting 2
= 4 units + 4 units
= 8 units
Measuring the distance from the entrance to painting 3 along the grid, we find:
Distance from entrance to painting 3
= 8 units
Hence, the painting that is 10 units away from the entrance is painting 1.
Now, the coordinates of painting 1, are: (3,10).
Therefore, the coordinates of the painting that is 10 units away from the entrance are (3,10).
