1]
d1 = 24 cm
d2 = 32 cm
K = 110 cm
s1 = s2 = 20 cm
L = 1/2 × d1 × d2
L = 1/2 × 24 × 32
L = 384 cm^2
jadi luas layang-layang Budi adalah 384 cm^2
s3 = s4 = 1/2 × (K – s1 – s2)
s3 = s4 = 1/2 × (110 – 20 – 20)
s3 = s4 = 1/2 × 70
s3 = s4 = 35 cm
jadi panjang sisi panjang layang-layang Budi adalah 35 cm

AB = 18 cm
BC = 10 cm
CD = 12 cm
CE^2 = BC^2 – (AB – CD)^2
CE^2 = 10^2 – (18 – 12)^2
CE^2 = 10^2 – 6^2
CE^2 = 100 – 36
CE^2 = 64
CE = V64
CE = 8 cm
AD = CE = 8 cm
K = AB + BC + CD + AD
K = 18 + 10 + 12 + 8
K = 48 cm
L = 1/2 × (AB + CD) × CE
L = 1/2 × (18 + 12) × 8
L = 1/2 × 30 × 8
L = 120 cm^2
catatan :
tinggi trapesium 6 cm salah yang benar 8 cm
karena tinggi trapesium = CE = AD = 8 cm
