We are given the perpendicular distances from point \( B \) to the x-axis and y-axis.
The perpendicular distance from a point to the x-axis gives the magnitude of the y-coordinate, while the perpendicular distance to the y-axis gives the magnitude of the x-coordinate.
Therefore, from the problem, the length of the perpendicular from point \( B \) to the x-axis is 10, which means the y-coordinate of \( B \) is 10.
Similarly, the length of the perpendicular from point \( B \) to the y-axis is 5, which means the x-coordinate of \( B \) is 5.
Thus, the coordinates of point \( B \) are \( (10, 5) \).
