From $23.5\text{ ft}$ to $24.5\text{ ft}$
The measurement is given to the nearest foot, so the error is $\pm\text{ 0.5 ft}$. Therefore, to find the range of values that the measurement represents, we must both subtract and add $0.5$ to the given value. $$24+0.5=24.5$$$$24-0.5=23.5$$ Therefore the range of values is from $23.5\text{ ft}$ to $24.5\text{ ft}$
