Menentukan panjang AB
2(AB + CD) = K
2(AB + 17) = 54
AB + 17 = 54/2
AB + 17 = 27
AB = 27 - 17
AB = 10 cm
Menentukan panjang AO
AO² = AB² - BO²
AO² = 10² - 6²
AO² = 100 - 36
AO² = 64
AO = √64
AO = 8 cm
Menentukan panjang CO
CO² = CD² - BO²
CO² = 17² - 6²
CO² = 289 - 36
CO² = 253
CO = √253 cm
Maka:
L = ½ × BC × AC
L = ½ × 12 × (8 + √253)
L = 6 × (8 + √253)
L = (48 + 6√253) cm²
