Question

Jawablah bangun diatas dengan caranya

Answer 1

1. p 9 l 7
luas = p × l = 9 × 7 = 63
kelil = 2 × p + 2 × l = 2×9 + 2×7 = 18 + 14 = 32

2. s = 8
luas = s×s = 8×8 = 64
kelil = s+s+s+s = 8+8+8+8 = 32

3. p 11 L 6
luas = p×l = 11×6 = 66
kelil = 2×p + 2×l = 2×11 + 2× 6 = 22 + 12 = 34

4. s= 12
luas = s×s = 12×12 = 144
kelil = s+s+s+s = 12+12+12+12 = 48

5.p 15 l 9
luas = p×l = 15×9 = 135
kelil = 2×p + 2×l = 2×15 + 2×9 = 30 + 18 = 48

1 yang bawah :
luas = p×l = 81×52= 4212
kelil = 2×p + 2×l = 2×81 + 2×52 = 162 + 104 = 266
