The width is given to 4 significant figures; whereas, the length is given to 2 significant figures. (the zero in the length is a place holder). According to the rules for significant figures, the result can only have 2 significant figures. Multiply the length by the width and express the result as 9200 m^2.

In case there is ambiguity as to how many significant figures there are, express the number in scientific notation. So, 280 m can be written as 2.8 x 10^2 which tells you there are only two significant figures.09/02/22
