Step-by-step explanation:
The subject of this question is Arts. More specifically, it relates to the technical aspects of stage design in a proscenium-style theatre. In a proscenium theatre, the leadroom refers to the space between the top of an actor's head and the upper edge of the stage.
For example, if an actor is standing on the stage and their head is near the upper edge, they have less leadroom. On the other hand, if their head is positioned lower on the stage, there is more leadroom.
The leadroom is important to ensure that actors are not cut off or obscured by the top of the stage, allowing for clear visibility between the actors and the audience.
