Answer 1

1. K = 9 cm + 4 cm + 15 cm + 15 cm

K = 43 cm

L = ½ × (9 cm + 4 cm) × 12 cm

L = ½ × 13 cm × 12 cm

L = 78 cm²

2. K = 5 cm + 5 cm + 8 cm + 4 cm

K = 22 cm

L = ½ × (8 cm + 5 cm) × 4 cm

L = ½ × 13 cm × 4 cm

L = 26 cm²

3. K = 5 cm + 5 cm + 7 cm + 7 cm

K = 24 cm

L = 7 cm × 4 cm

L = 28 cm²

4. K = 8 cm + 8 cm + 12 cm + 12 cm

K = 40 cm

L = 12 cm × 5 cm

L = 60 cm²

5. d = 7 cm, maka r = 7:2 = 3,5 cm

K = 22/7 × 7 cm

K = 22 cm

L = 3,14 × 3,5 cm × 3,5 cm

L = 38,465 cm²
