What is the calculation for mechanical advantage on this inclined plane:

• The mechanical advantage of an inclined plane is equal to the length of the slope divided by the height of the inclined plane.

• The mechanical advantage of an inclined plane is equal to the length of the slope added by the height of the inclined plane.

• The mechanical advantage of an inclined plane is equal to the length of the slope divided by the height of the inclined plane.

• The mechanical advantage of an inclined plane is equal to the length of the slope subtracted by the height of the inclined plane.
