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
