24,25 n 26 thx plus cara y
poin 30 lho

Answer 1

24. L.Bangun 1 = 8 * 30 = 240 cm²     L.Persegi = 2 (8*30) = 2.240 = 480 cm²
      L.Bangun 2 = 8 * 30 = 240 cm²     
      L.Bangun 3 = 8 * 6 = 48 cm²        L.Segitiga = 2 (8*6) = 2.48 = 96 cm²
      L.Bangun 4 = 8 * 6 = 48 cm²         
 
      L.Total = 240 + 240 + 48 + 48      L.Total = 480 + 96 = 576 cm²
                 = 576 cm²

Answer 2

24)  L1 = 30 × 16 = 480 cm²
       L2 = 16 × 6 = 48 cm²
                   2
       48 + 48 = 528 cm² (D)
25) L perseginya = 22²  = 484 cm²
      L segitiga = 10 × 22 = 110 cm²
                                2
      L trapesium = (22 + 12) × 12 = 204 cm²
                                       2
      = 484 - 110 - 204 = 170 cm² (C)
26 )  3,14 × 63 × 63 × 1   = aku ketemunya 4.154,22
