Answer:

C.) [tex]1.8\times10^5\ cm^2[/tex]

Step-by-step explanation:

-The area of a rectangle is given by the product of it's length and width.

-Given the length is  9⋅10^2 cm and the width is 2.10^2 cm, the area can be calculated as:

[tex]A=lw\\\\=(2\times 10^2)\times(9\times 10^2)\\\\=1.8\times 10^5\ cm^2[/tex]

Hence, the rectangle has an area of [tex]1.8\times10^5\ cm^2[/tex]
