Tolong ya kak
buat ukk mtk
Penjelasan dengan langkah-langkah:
BO = BD / 2
BO = 16 / 2
BO = 8 cm
BO = OD = 8 cm
a] AO = √(AD² – OD²)
AO = √(10² – 8²)
AO = √(100 – 64)
AO = √(36)
AO = 6 cm
OC = √(CD² – OD²)
OC = √(17² – 8²)
OC = √(289 – 64)
OC = √225
OC = 15 cm
Panjang AC
= 6 + 15
= 21 cm
Luas layang-layang ABCD
= 1/2 . AC . BD
= 1/2 . 21 . 16
= 168 cm²
b] Keliling ABCD
= 2 . (AD + DC)
= 2 . (10 + 17)
= 2 . 27
= 54 cm
