L 1/2 lingkaran = 1/2 x phi x r2 = 1/2 x 22/7 x 7 x 7 = 77 cm2 L persegi = s x s = 14 cm x 14 cm = 196 cm2 L bangun tersebut = 77 cm2 + 196 cm2 = 273 cm2

L=luas ½ lingkaran+luas persegi =½X22/7X14X14+14X14 =308 + 196 =504cm^2
L 1/2 lingkaran = 1/2 x phi x r2 = 1/2 x 22/7 x 7 x 7 = 77 cm2
L persegi = s x s = 14 cm x 14 cm = 196 cm2
L bangun tersebut = 77 cm2 + 196 cm2 = 273 cm2
=½X22/7X14X14+14X14
=308 + 196
=504cm^2
