From measurements in a microscope, you determine that a certain bacterium covers an area of 1.50 μm2. Convert the area into square meters. Show your solution.

So the problem ask to find and convert the area into square meters. So to convert is you must do the cross multiplication process that could cancel out unit and made the answer into a square meter, so the answer would be 1. x10^-12m^2. I hope you are satisfied with my answer and feel free to ask for more
