tolong di jawab beserta caranya

23. B. III
24. L = p × l = 27 × 12 = 324 cm² "D"
25. L persegi panjang = p × l = 45 × 25 = 1.125 cm²
L segitiga = 1/2 × a × t = 1/2 × 25 × 30 = 375 cm²
L total = 1.125 cm² + 375 cm² = 1500 cm² "A"
26. L = 3/4 × π × r² = 3/4 × 22/7 × 28 × 28 = 1.848 cm² "C"
27. V = p × l × t = 400 × 12 × 6 = 28.800 cm³ "D"
