To put it simply, it follows the rule that the lesser the force needed, the greater the distance. The work that is done moving an object will always be the same with or without a machine to help. When the force decreases in the formula work = force x distance, the distance will increase. When the force increases, the distance decreases.
The same logic is applied here. In the second picture, the slope is steeper and has less distance to cover to arrive on the top of the blue box. The force has increased, but the distance has decreased. in the first picture, the force has decreased and the distance, increased, as the slope is less steep.
The force decreases when compared to lifting the object straight up because when using an inclined plane, you are pushing the object and counteracting gravity instead of having to overcome the full force of gravity.
