Diketahui :

- Trapesium :
• a = 28 cm
• b = 40 cm
• sisi samping = 32 x 2 = 64 cm

- ½ Lingkaran :
• d = 28 cm

Ditanya :
- K Total

KT = a + b + sisi samping
KT = 28 + 40 + 64
KT = 68 + 64
KT = 132 cm

KL = ½ x π x d
KL = ½ x 22/7 x 28
KL = ½ x 22 x 4
KL = 11 x 4
KL = 44 cm

K Total : 132 + 44
K Total : 176 cm

Jawaban : 176 cm

Heil Manstein!

28+40×32=21.176:2=10.588
22/7×28=616:7=88×1/2=44
jadi 10.588-44=10.544
maaf kalo salah
