    Ok im having problem with this problem.

    Some students made a map of the area around their school. They made it on graph paper and put the school in the middle square on the map. The square with the school was the sixth square from the top of the map and the fourth from the right-hand side. How many squares are on the map?

    Assuming the middle square is exactly in the middle:

    Vertically: \frac{n + 1}{2} = 6
    Thus 11 squares vertically.

    Horizontally: \frac{n + 1}{2} = 4
    Thus 7 squares horizontally.

    11 x 7 = 77 squares.
