tlong yaaa bantuuuu pliss

Penyelesaian :

Panjang CD
[tex] = \sqrt[2]{ {34}^{2} - {16}^{2} } \\ = \sqrt[2]{1156 - 256} \\ = \sqrt[2]{900} = 30 \: \: cm[/tex]

Panjang BD
[tex] = \sqrt[2]{ {50}^{2} - {30}^{2} } \\ = \sqrt[2]{2500 - 900} \\ = \sqrt[2]{1600} = 40 \: \: cm[/tex]

Panjang AB
= AD + BD
= 16 cm + 40 cm
= 56 cm
Opsi => B
