300' x 300' = 90,000 square feet
The question, as stated, cannot be answered sensibly. A square metre is a measure of area, with dimensions [L2]. A foot is a measure of distance, with dimensions [L]. The two measure different things and elementary dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
300 (square meters) = 3,229.2 square feet.
