tolong jawab pake cara y please

Penyelesaian :
Luas persegi
= s × s
= 14 cm × 14 cm
= 196 cm^2

Luas 1/2 lingkaran
= 1/2 × phi × r^2
= 1/2 × 22/7 × 7 cm × 7 cm
= 77 cm^2

Luas 1/4 lingkaran
= 1/4 × phi × r^2
= 1/4 × 22/7 × 14 cm × 14 cm
= 154 cm^2

Luas gabungan
= 196 cm^2 + 77 cm^2 + 154 cm^2
= 427 cm^2
Opsi => C

Good Luck :)

L1=Luas Persegi = s × s = 14 × 14 = 196
L2 = Luas lingkaran = π × r × r = 22/7 ×7 ×7 ×1/2 =77cm
L3 = Luas Lingkaran = π × r × r =22/7 × 14 × 14 ×1/4 = 154
L1 +L2+L3 = 196 + 77 +154 = 427 Jawabannya C

Semoga Membantu :)
