I have a linear operator $T:\mathbb{R}^3\rightarrow \mathbb{R}^2$ defined by $T\begin{bmatrix}x\\y\\z \end{bmatrix}=\begin{bmatrix}1&0&0\\0&1&1\end{bmatrix}\begin{bmatrix}x\\y\\z\end{bmatrix}.$ The domain and codomain spaces are having Euclidean norms on them. Then what is the norm of $T.$ The definition for a norm here is $\|T\|=sup \Big\{\frac{\|Tv\|_2}{\|v\|_2} \hspace{0.05 cm}:v\neq 0\Big\}$
