Final answer:
The subject of this question is related to construction and specifically the design and measurement of landings on stairways. In stair construction, it is generally recommended that every landing should be at least 15 inches measured in the direction of travel, and the width should not be less than the width of the stairway.
Step-by-step explanation:
The subject of this question is related to construction and specifically the design and measurement of landings on stairways.
In stair construction, it is generally recommended that every landing should be at least 15 inches measured in the direction of travel. This measurement ensures that the landing provides enough space for a person to stand or step comfortably. Additionally, the width of the landing should not be less than the width of the stairway, ensuring a safe and proportional design.
Example: If a stairway is 36 inches wide, the landing should also be 36 inches wide or wider.
