cari dulu luas persegi panjang
luas persegi panjang
= p × l
= 22 × 6
= 132 cm 2
terus cari luas lingkaran
dikarenakan diameter belum diketahui
maka panjang persegi panjang - 8 cm
= 22 - 8
= 14
maka diameter = 14 atau jari jari = 7
luas lingkaran
= π × r2
= 22/7 × 49
= 154 cm
setengah lingkaran = 154 : 2 = 77
luas seluruh = 132 + 77 = 209 cm2
semoga membantu
