Answer 1

1. keliling: 22/7 x 28 = 88
luas: 22/7 x 14 x 14 = 616

Answer 2

1) k = 22/7 × 28
= 88cm
L = 22/7 × 14 × 14
= 616 cm²

2) k = 22/7 × 42 = 132 cm
L = 22/7 × 21 × 21 = 1386 cm²

3) k = 22/7 × 56 = 176 cm
L = 22/7 × 28 × 28 = 2464 cm²

4) k = 22/7 × 70 = 220 cm
L = 22/7 × 35 × 35 = 3850 cm²

5) k = 3,14 × 20 = 62,4 cm
L = 3,14 × 10 × 10 = 314 cm²

6) k = 3,14 × 40 = 125,6 cm
L = 3,14 × 20 × 20 = 1256 cm²

7) k = 3,14 × 30 = 94,2 cm
L = 3,14 × 15 × 15 = 706,5 cm²

8) k = 3,14 × 40 = 125,6 cm
L = 3,14 × 20 × 20 = 1256 cm²

9) k = 22/7 × 56 = 176 cm
L = 22/7 × 28 × 28 = 2464 cm²

10) k = 3,14 × 48 = 150,72 cm
L = 3,14 × 24 × 24 = 1808,64 cm²
