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

I think your best answer is a pasture that is 75 feet by 150 feet, which will give you 11,250 sq ft of pasture
