Luas persegi = s²
= 7²
= 49 cm²
Luas lingkaran = πr²
= 22/7 × 7²
= 154 cm²
2 Luas ¼ lingkaran = ½πr²
= ½ × 154
= 77 cm²
Luas total
= Luas persegi + Luas Lingkaran - 2 Luas ¼ lingkaran
= 49 + 154 - 77
= 126 cm²
Keliling:
Keliling lingkaran = 2 × π × r
= 2 × 22/7 × 7
= 44 cm
Keliling total = Keliling lingkaran + 7 + 7 + 7 + 7
= 44 + 28
= 72 cm
Jadi,
Luas total = 126 cm²
Keliling total = 72 cm
