tolong dijawab yg 36 pke cara, trimakasih

LM² = LN² - MN²
LM² = 17² - 15²
LM² = 289 - 225
LM² = 64
LM = √64
LM = 8 cm

Luas KLMN = LM x MN
Luas KLMN = 8 cm x 15
Luas KLMN = 120 cm²

Jawabannya A

LN = 17
MN = 15
MNL adalah segitiga siku2 di M
jadi menggunakan rumus Pythagoras

[tex] {ln}^{2} = {mn}^{2} + {ml}^{2} [/tex]
[tex] {17}^{2} = {15}^{2} + {ml}^{2} [/tex]
[tex] {ml}^{2} = {17}^{2} - {15}^{2} \\ {ml}^{2} = 289 - 225 \\ {ml}^{2} = 64 \\ ml = \sqrt{64} = 8[/tex]
Luas persegi panjang = MN x ML = 15 x 8 = 120
