Penjelasan dengan langkah-langkah:
1. 7 + 9 + (19-7) + 9 + 5 + 5 + (9+6) + 19 + 9 + 7 + (9+9+6) = 121
2. 16 + 12 + (16+9) + (√9²+12²) + 11 + 11 = 90
3. Lbiru = s² = 10² = 100
Lungu = ½. jmlh // . t = ½. (10+22) . √10²-((22-10)/2)² = ½.32.√10²-(12/2)² = ½.32.√100-6² = 16.8 = 128
jumlh total luas = 100 + 128 = 228
