This question cannot be answered as a meter is a straight line in a one dimensional plain. Nothing is 2 dimensional or lower unless it is a theoretical idea, as everything has length, width, and height. Since a meter is an idea of a line inbetween two theoretical points it cannot be place side by side with other meters to make a square meter.
If you were to solve this mathematically with x = 1 meter and y = 1 square meter
x2 = y
