Jawaban : C
2. K = jumlah sisi jajargenjang
K = 2(75+30) = 210 dm
Jawaban : B
3. L = a x t
L = 10 x 7
L = 70 cm2
Jawaban : B
4.

8. K = jumlah sisi segitiga
K = 8 + 12 + 15 = 35 cm
Jawaban : A
9. K = jumlah sisi segitiga
K = 2(AB) + BC
K = 2(12) + 8
K = 24 + 8
K = 32 cm
Jawaban : C
10. K = jumlah sisi segitiga
50 = 2(15) + KM
50 = 30 + KM
KM = 50 – 30

KM = 20 cm
