You simply can't convert between linear units and square units.
Multiply yards by 0.9144 to get meters.
Yards x 0.9144 = meters
yards x 0.9144 = meters
Meters x 1.09361 = yards
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.
100 meters = 109.36133 yards
Multiply the number of meters by 1.0936 to get the number of yards.
About 4000 yards.
Eight meters is 8.75 yards.
25 yards = 22.86 meters.
50 meters = 54.6806649 yards
6.25 yards = 5.715 meters
