The correct answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

To determine the minimum length of a ramp required to provide access to a door that is 5.2 feet above the sidewalk, you need to understand the slope requirement set by the Americans with Disabilities Act (ADA). The ADA specifies that the maximum slope for a wheelchair ramp is 1:12. This means that for every 1 unit of vertical rise, there must be at least 12 units of horizontal run.<\/p>\n\n\n\n

Here\u2019s the step-by-step process to find the minimum length of the ramp:<\/p>\n\n\n\n

    \n
  1. Identify the Vertical Rise:<\/strong>
    The vertical rise of the ramp is given as 5.2 feet.<\/li>\n\n\n\n
  2. Apply the Slope Ratio:<\/strong>
    The slope ratio of 1:12 means that for every 1 foot of rise, the ramp must extend 12 feet horizontally. Therefore, to calculate the minimum length of the ramp (which is the hypotenuse of a right triangle where the rise is one leg and the run is the other), use the formula: [
    \\text{Length of Ramp} = \\text{Vertical Rise} \\times \\text{Slope Ratio}
    ] In this case: [
    \\text{Length of Ramp} = 5.2 \\text{ feet} \\times 12
    ] [
    \\text{Length of Ramp} = 62.4 \\text{ feet}
    ]<\/li>\n<\/ol>\n\n\n\n

    Thus, the minimum length of the ramp required is 62.4 feet.<\/p>\n\n\n\n

    Explanation:<\/strong><\/p>\n\n\n\n

    To comply with the ADA\u2019s 1:12 slope requirement, the ramp must be long enough to ensure that its slope does not exceed the prescribed limit. The ratio ensures that individuals using wheelchairs or mobility aids can ascend or descend safely and comfortably without excessive effort. If the ramp were shorter, it would be steeper, making it difficult or impossible for many users to navigate. Conversely, a ramp longer than necessary would still meet the requirement but might be more space-consuming than needed. Hence, the calculated length of 62.4 feet ensures accessibility while adhering to the ADA standards.<\/p>\n","protected":false},"excerpt":{"rendered":"
