## Computer program

The area of the aspen leaf is 9.902 cm^{2}, which includes the leaf trunk. The length of the leaf without the trunk is 41.547 mm.

**Next, the determinations of the areas of the colored parts of the autumn aspen leaf**

**Green areas:**

* green* area of the leaf is 7.569 cm

^{2}, i.e. 7.569 / 9.902 × 100% = 76.4% of the remaining green area denoted by red color.

**Yellowed and darkened areas, probably caused by fungi and bacteria: **

The * yellowed* area of the leaf is 0.600 cm

^{2 }i.e. 6.1% of the total leaf area (red areas).

* darkened* area of the leaf is 1.726 cm

^{2}i.e. 17.4% of the total surface area of the leaf (red areas).
