1.Diketahui
p=45 cm
l=36 cm
Ditanya Luas=p×l
=45×36=1620 cm²

1) L = p × l = 45 × 36 = 1620 dm²

2) maaf , angka kurang jelas

3) L = a × t
240 = 16 × t
t = 240 ÷ 16
t = 15 cm

4) L1 = p × l = 18 × 25 = 450 cm²
L2 = ½ × d1 × d2 = ½ × 18 × 25 = 225 cm²
L d = 450 - 225 = 225 cm²

5) L1 = s² = 28 × 28 = 784 cm²
L2 = π × r² = 22/7 × 14 × 14 = 616 cm²
L d = 784 - 616 = 168 cm²

6) V = π × r² × t
= 3,14 × 20 × 20 × 50
= 62.800 cm³

7) gambar kurang jelas

8) V = ½ × a × ta × tp
3.000 = ½ × 10 × 15 × tp
3.000 = 75 tp
tp = 40 cm

9) V = π × r² × t
= 22/7 × 7 × 7 × 24
= 3696 cm³
