Answer:
781200 cm or 7.81200x10^5 cm
Step-by-step explanation:
Here, you need to solve it with the area equation.
For a rectangle, it's base x height.
In this case, your base will be it's length [tex]9.3x10^{2} cm[/tex] = [tex]930cm\\[/tex], and its height will be width [tex]8.4x10^{2} cm[/tex] = [tex]840cm[/tex].
An then you can solve it
[tex](9.3x10^{2})*(8.4x10^{2})=781200 cm = 7.81200x10^{5}[/tex]
