Marat540 [252]

Answer: 19.13 yd²

Step-by-step explanation:

1. By definition,  you have that 1 square meter is equal to 1.19599 square yards. You can express it as following:

1 m²= 1.19599 yd²

2. Then, keeping the information above on mind, you can make the conversion from 16 m² to yd² as it is shown below:

(16m^2)(\frac{1.19599yd^2}{1m^2})=19.13yd^2

Therefore, you have that 16 m² is equivalent to 19.13 yd².
