To find the magnitude, we have to use the following formula


|d|=\sqrt[]{x^2+y^2}

Where x = 1 and y = 3, let's use these values to find the magnitude.


\begin{gathered} |d|=\sqrt[]{1^2+3^2}=\sqrt[]{1+9}=\sqrt[]{10} \\ |d|\approx3.2 \end{gathered}

The magnitude of the resultant vector is 3.2 meters, approximately.

To find the direction, we have to use the following formula


\begin{gathered} \theta=\tan ^(-1)((y)/(x))=\tan ^(-1)((3)/(1)) \\ \theta\approx71.6 \end{gathered}

The direction of the resultant vector is 71.6°.
