Jawab:
300
Penjelasan dengan langkah-langkah:
keliling layang-layang= 2 (AD + AB)
70 = 2 (AD + 20)
70 = 2AD + 40
30 = 2AD
AD = 15
AC = 24
O = pusat
AO = 24/2 => 12
AB = 20
BO =
BO = 16 cm
OD =
OD = 9 cm
BD = 16 + 9
BD = 25 cm
luas layang-layang = x d1 x d2
luas layang-layang = x AC x BD
= x 24 x 25
= 300
