the length of the tv screen is,

l = 41 cm

the width of the tv is

b = 31 cm

the length of the diagonal will be the hypotenuse of the triangle,

so, diagonal length is,


\text{diagonal}=\sqrt[]{41^2+31^2}
\text{diagonal}=\sqrt[]{1681+961}
\begin{gathered} \text{diagonal}=\sqrt[]{2642} \\ \text{diagonal}=51.04 \end{gathered}

so, the length of the diagonal is closest 51.04 cm
