9. Dengan Menggunakan Teorema Pythagoras
QS² = QR² - RS²
QS² = 20² - 16²
QS² = 400 - 256
QS² = 144
QS = akar 144
QS = 12 cm
SP² = QS² + PQ²
SP² = 12² + 9²
SP² = 144 + 81
SP² = 225
SP = akar 225
SP = 15 cm
K = TOTAL SEMUA SISI LUAR
K = 15 + 9 + 20 + 16 cm
K = 60 cm
10. Menggunakan Rumus Segitiga
Lbcd = 1/2 x 5 x 8
Lbcd = 20 cm²
Lacd = 1/2 x 15 x 8
Lacd = 60 cm²
Labd = Lacd - Lbcd
Labd = 60 - 20 cm²
Labd = 40 cm²
