Answer 1

4.
Keliling = jumlah semua sisi
K = 3 + 6 + 4 + 6 + 5
K = 24 cm

5.
Luas gabungan = L persegi + L segitiga
L gab = s x s + 1/2 x a x t
L gab = 8 x 8 + 1/2 x 6 x 8
L gab = 64 + 24
L gab = 88 cm2

Answer 2

Jawaban

4. Keliling Trapesium = AB + BC + CD + AD

AB = 3 + 6 = 9

BC = 4

CD = 6

AD = 5

Di jawab = AB + BC + CD + AD

9 + 4 + 6 + 5

24 cm

5. Luas Trapesium = ½ × a × t

a = 8 + 6 = 14

t = 8

Di jawab = ½ × a × t

½ × ( AB + BC ) × t

½ × ( 8 + 14 ) × 8

½ × 22 × 8

11 × 8

88 cm
