To find the total area available for printing, we need to subtract the area of the margins from the total area of the pages.

The total area of the pages can be found by multiplying the length and width of each page and then multiplying by the number of pages: Total area of pages = (20 cm - 2 * 2.5 cm) * (14 cm - 2 * 2 cm) * 360 pages

Simplifying the equation: Total area of pages = (20 cm - 5 cm) * (14 cm - 4 cm) * 360 pages Total area of pages = 15 cm * 10 cm * 360 pages

Now, we can calculate the total area available for printing: Total area available for printing = Total area of pages Total area available for printing = 15 cm * 10 cm * 360 pages Total area available for printing = 5400 cm² * 360 pages

Therefore, the total area available for printing is 1,944,000 cm².
