Hitunglah luas dan keliling bangun datar gabungan dibawah ini?

● Keliling :
K = 9+8+6+4+6+8+9+20
K = 70 cm

● Luas :
L1 → p = 9cm, l = 8cm
L1 = p x l
L1 = 9 x 8
L1 = 72 cm²

L2 → p = 9+6 = 15cm, l = 4cm
L2 = p x l
L2 = 15 x 4
L2 = 60cm²

L3 → p = 9cm, l = 8cm
L3 = p x l
L3 = 9 x 8
L3 = 72cm²

L keseluruhan = L1 + L2 + L3
L keseluruhan = 72 + 60 + 72
L keseluruhan = 204 cm²
