The given values of this problem are:
Length = 19. 5 cm
Width (diameter) = 0.6 cm

The unknown is: how much square cm of plastic are used in one straw? In other words the area of the straw.

Derivations and solutions:

Area = length x width
Area = 19. 5 cm x 0.6 cm

Area = 11.7 cm(squared) / 11.7 cm^2
