#120000"cm"^2#

To convert meters to centimeters, multiply by #100#.

To convert square meters to square centimeters, multiply by #100^2 = 10000#.

In our example, we can reexpress the base of the parallelogram as #400"cm"# and the height as #300"cm"#

Then the area is:

#"base" xx "height" = 400"cm" xx 300"cm" = 120000"cm"^2#

Alternatively, we can do the calculation in square meters first:

#"base" xx "height" = 4"m" xx 3"m" = 12"m"^2 = 120000"cm"^2#
