A scale of 1:20 indicates what relationship between landscape measurements and blueprints?

1. 5' of landscape equals 6" of blueprint

2. 2' of landscape equals 1 1/2" of blueprint

3. 1" of blueprint equals 20' in the landscape

4. 1" of blueprint equals 30" in the landscape

The correct answer is: 1" of blueprint equals 20' in the landscape

A scale of 1:20 means that 1 unit of measurement on the blueprint corresponds to 20 of the same units in reality. This is a common way to represent measurements in landscape design and architecture. In this case, if you have 1 inch on the blueprint, it represents 20 inches in the actual landscape, since there are 12 inches in a foot, this can also be understood as 1 inch on the blueprint representing 20 feet in the landscape. This relationship is crucial for translating the dimensions of a plan into real-world measurements, allowing landscapers and architects to convey their designs accurately. Other choices do not correctly reflect this scale. For example, they either misinterpret the ratio or use incorrect measurements that do not align with the scale relationship provided. Understanding this relationship helps in implementing measurements accurately when executing landscaping projects.
