Final answer:
The question from Mathematics requires counting the number of non-square rectangles that can be formed from six unit squares. Starting from rectangles covering two unit squares and avoiding counting squares or duplicates, each possibility needs to be carefully considered to reach the accurate count.
Step-by-step explanation:
The subject of the question is Mathematics, and it is at a Middle School level. The task is to determine how many different non-square rectangles can be formed using the lines of six unit squares arranged in a given format. To solve this, one has to consider each possible combination of unit squares that can form a rectangle without forming a square shape. Rectangles can differ by length and width, and these dimensions are determined by how many unit squares are lined up along each axis.
To count the number of non-square rectangles, we look at the possibilities. For example, rectangles spanning two squares in one direction and one square in another count as non-square rectangles. Keeping in mind that squares are not to be counted, we can systematically work through the combinations:
- Rectangles that cover two contiguous unit squares: there are several of these, each having different positions.
- Rectangles that cover three, four, or more contiguous unit squares in a row, or stacked in two or more rows.
Without a visual representation of the unit squares, it's challenging to provide an exact number, but the general approach is to count all the combinations that meet the criteria while avoiding counting squares or the same rectangle in different orientations.
