From the given information, A is a point with co-ordinates (3,-2, 3).

If you consider the projection of A(3,-2,3) on the XY-plane is H(3,-2,0) where the z-coordinate will not exist on XY-plane.

Similarly projection of A(3,-2,3) on the YZ-plane is T(0,-2,3) where the x-coordinate will not exist on YZ-plane.

The projection of A(3,-2,3) on the XZ-plane is T(3,0,3) where the x-coordinate will not exist on XZ-plane.

Now, the distance between A and XY-plane = Distance between points A&H

Distance between two points is given by

Using this formula,

Distance of point A from XY

= √ 3²

= 3

Distance of point A from YZ

= √ 3²

= 3

Distance of point A from XZ

= √ 2²

= 2
