parallelogram

The side length of square ABCD is 1cm. It is a visual picture of a plane figure placed horizontally. What is the perimeter of the original shape

In the visual graph, the horizontal line is one according to the original one, while the other is rotated 45 degrees to the right, and the length is half of the original length. Now the vertical side of the square is rotated 135 degrees, and the length should be 2, so the perimeter of the original shape (a parallelogram) should be 1 + 2 + 1 + 2 = 6

Take the square with the side length of 1cm as shown in the figure below, one layer, two layers, three layers Put together all kinds of figures. This figure has four parts
Why the answer

The perimeter of the first floor is 4
You can see the perimeter of the second floor and cover the one under the first floor, right? Let's replenish the first floor with the one under the second floor on the lower right
Then the perimeter of the second floor is more than that of the first floor, which is the perimeter of the square in the lower left corner without the right side, plus the vertical edge on the rightmost side of the second floor
Then the total perimeter of the second floor is regarded as the perimeter of two independent small squares and 2 * 4 = 8
Three levels of the same reason, the lower right two horizontal edges are filled with two more levels of the covered one more complete small square
Perimeter 3 * 4 = 12
4 * 4 = 16
If there are n layers, then n * 4 = 4N
Please accept~

As shown in the figure, the side length of the square o'a'b'c'is 1cm, which is a visual picture of a plane figure placed horizontally, then the perimeter of the original figure is ()
A. 8cmB. 6cmC. 2（1+3）cmD. 2（1+2）cm

According to the rule of oblique dichotomy, the length of a line segment parallel to the X 'axis and the property parallel to the horizontal axis remain unchanged. If the diagonal of a square is on the Y' axis, its length can be obtained to be 2. Therefore, in a plane graph, it is on the Y axis, and its length becomes 2 times of the original length, which is 22. If the original graph is as shown in the figure, then the original graph
