Answer :
We are given that the diagonal of the monitor is
$$\sqrt{290}.$$
First, we approximate its value. We have
$$\sqrt{290} \approx 17.03.$$
To find the monitor size as measured by the diagonal, we round this value to the nearest whole number. Since $17.03$ is closest to $17$, the rounded value is
$$17.$$
Thus, the monitor size is $\boxed{17}$ inches.
