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.

There are 2.54 centimetres in one inch. Therefore, a measurement of 6 inches on one side and 4 inches on the other would give side-measurements of 6 x 2.54 = 15.24 x 10.16 centimetres.
If it is a rough measure then you can say it is 10 x 15 cm.
Exactly, it is 10.16 x 15.24 cm.
(1 inch = 2.54 cm.)
first product is calculated = 6 X 4 =24 sq.inches .
Now ,convert 1 sq .in =6456.16 sq.mm .
24 sq .in =15484 sq.mm.
A = area = ( 6 mm ) ( 8.3 mm ) = 49.8 mm^2
A = ( 49.8 mm^2 ) ( 1 in / 25.4 mm )^2
A = 0.07719 in^2 <------------------------------
