It would be more like�16 %.� A yard is 0.9144 m,�thus�a square yard is 0.836 127 m^2� or 16.4 % smaller.

<x-tad-smaller>Hello could someone please tel me if a square meter is approx 10% larger than a square yd? I have heard that another rule of thumb is that a meter is approx 10 % longer than a yd.� A yd plus 10 % is 39.36 in. A meter is 10 % longer than a yd minus .23�of an inch.� Close enough for every day use.� ������</x-tad-smaller>
Euric's value is based on the percentage as compared to the square metre. But as the question was asked, it is implied that the percentage is intended to be the percentage compared to the square yard.
The square yard is 0.83 square metres (as Euric correctly notes above). That is different from a square metre by 0.17 square metres. To find that difference expressed as a percentage OF A SQUARE YARD one needs to divide the 0.17 m^2 difference BY A SQUARE YARD (or it's equivalent in square metres). Thus the percentage is found by dividing 0.17 by 0.83 (and shifting the decimal point 2 places) to get 20%, not 16% reported by Euric.
Euric's figure of 16.4% apparently came from dividing 0.17 m^2 by 1.00 m^2. (When I divide those two I get 17% but Euric and I rounded off differently earlier in the calculation so he got 16.4% instead of 17%. Since it should have been 20%, the difference between 16.4% and 17% doesn't seem to matter.)
