Answer
From $33.5\text{ yd}^2$ to $34.5\text{ yd}^2$
Work Step by Step
The measurement is given to the nearest $1$ square yard, so the error is $\pm0.5\text{ yd}^2$. Therefore, to find the range of values that the measurement represents, we must both subtract and add $0.5$ to the given value. $$34+0.5=34.5$$$$34-0.5=33.5$$ Therefore the range of values is from $33.5\text{ yd}^2$ to $34.5\text{ yd}^2$
