Answer:
9.29 x 10^-2 it's wrong. It's 9.29 x 10^2 (positive)
Step-by-step explanation:
You can "move" or change the measure of everything using some scales based on specific boards.
There's a way to move from the imperial system (yards, feet, inches) to the metric system ( centimeters, meters, kilometers)
1 square foot = 929.03 square centimetre
929.03 can be written with the scientific notation, taking care of the significant figures like [tex]9.29x10^{2}[/tex]
3 [tex]feet^{2}[/tex] = 2787.09 [tex]cm^{2}[/tex] or [tex]27.87x10^{2}[/tex] [tex]cm^{2}[/tex]
