Question

directions: write the measurement indicated using the picture of the architectural scale.1.2.3.

Explanation:

Step1: Read the scale

For architectural scales, we look at the markings. The scale here is in feet (assuming standard architectural scale). Each major mark is a certain value.

Step2: Calculate the measurement for 1

The starting point is \(84\) and the ending point is \(0\). The difference is \(84 - 0=84\). But wait, no, actually, looking at the scale, when using the \(1/4\) scale (which means \(1/4\) inch = \(1\) foot). The length from the start (left - hand mark) to the end (right - hand mark) for problem 1: The left - hand mark is at \(84\) and the right - hand mark is at \(0\). The number of units between them. Each unit on the \(1/4\) scale (the numbers \(84,88,\cdots\)) represents \(4\) feet. The number of \(4 -\)foot units from \(84\) to \(0\) is \(21\) (since \(84\div4 = 21\)). But wait, another way: The scale is read as follows. The arrow starts at \(84\) and ends at \(0\). The value is \(84\) feet.

Step3: Calculate the measurement for 2

The arrow starts at \(92\) and ends at \(0\). Using the same scale (each number represents \(4\) feet, since \(80 - 76=4\)). The value is \(92\) feet.

Step4: Calculate the measurement for 3

The arrow starts at \(80\) and ends at \(0\). The value is \(80\) feet.

Answer:

1. \(84\) feet
2. \(92\) feet
3. \(80\) feet
