1 inch = 25.4 mm

8 in = 8 x 25.4

= 203.2 mm

4 in = 4 x 25.4

= 101.6 mm

8 in x 4 in = 20 645 mm2

=20.645 cm2

ANSWER:

As far as the question is concerned 8/4= 2 it has got no units as the one in the numerator cancels the one in the denominator so it has no units but has a magnitude which is equal to 2.
