You simply can't convert between linear units and square units.
There is no sensible answer to this question. A square yard is a measure of area, with dimensions [L2]. A lineal metre is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions without additional information.
Multiply yards by 0.9144 to get meters.
Yards x 0.9144 = meters
Meters x 1.09361 = yards
yards x 0.9144 = meters
100 meters = 109.36133 yards
6.25 yards = 5.715 meters
2.31 meters is about 2.526 yards
10.5 yards = 9.6012 meters
5.12 meters=5.59930009 yards
7.52 meters = 8.22 yards.
10,000 yards = 9,140 meters
