Tolong bantuan nya ya!

DIK :
K = 52 cm
diagonal 1 = 24 cm

DIT :
L = ?

[tex]k = 4 \times s \\ 52 = 4 \times s \\ s = 52 \div 4 \\ s = 13 \: cm[/tex]

[tex] {x}^{2} = {13}^{2} - {12}^{2} \\ {x}^{2} = 169 - 144 \\ {x}^{2} = 25 \\ x = \sqrt{25} \\ x = 5 \: cm[/tex]

[tex]panjang \: diagonal \: 2 \\ = 2 \times 5 \\ = 10 \: cm[/tex]

[tex]l = \frac{diagonal \: 1 \times \: diagonal \: 2 }{2} \\ l = \frac{24 \times 10}{2} \\ l = 120 \: {cm}^{2} [/tex]

SEMOGA MEMBANTU :)
