because I don’t understand?

Actually, there is not much to understand. You just have to do what it says.

a) Simply read the coordinates in the graphic:
x = 4
y = 0

Solution: B(4/0)

(b) Just play a bit around to get three equal (concrete) triangles. It would be useful to start with a horizontal LKinie from A:

Now you have a triangle with the two cedes of 3 cm and 4 cm in length. Now consider how you can pull a line up so that you can get two additional equally large triangles.

(c) Just count the corners of the figure. This is also the solution.

(d) You can calculate the area separated from the rectangle above and the triangle below and then count both together.

(e) 18 was the size. Of these, the 3 routes are deducted. What’s left? For this purpose, simply use the fingers or the figure accordingly.

c) Rectangle is already, is probably trapezoidal

The answer to task c) is:

Trapeze

A = 3 * 4 + 1/2 * 3 * 4 = 12 + 6 = 18 cm^2
