[tex]\sf{Diagonal}[/tex] = [tex]\sf{\sqrt{P² × \ell²}}[/tex]

[tex]\sf{Diagonal}[/tex] = [tex]\sf{\sqrt{12² + 8²}}[/tex]

[tex]\sf{Diagonal}[/tex] = [tex]\sf{\sqrt{(12 × 12) + (8 × 8)}}[/tex]

[tex]\sf{Diagonal}[/tex] = [tex]\sf{\sqrt{144 + 64}}[/tex]

[tex]\sf{Diagonal}[/tex] = [tex]\sf{\sqrt{208}}[/tex]

[tex]\sf{Diagonal}[/tex] = [tex]\underline{\boxed{\red{\bf{4 \sqrt{13}~cm}}}}[/tex]
