Математика номер 322(1) Сколько прямоугольников на чертеже?

I don't know the specific answer to the question you asked. However, to determine the number of rectangles in a drawing, you can count the number of pairs of parallel lines and multiply it by the number of pairs of perpendicular lines. Keep in mind that this method assumes that all the lines in the drawing are straight and that there are no diagonal lines.
