Keliling persegi panjang = 2 x ( p+ l ) = 2 x ( 30 + 14 ) = 2 x 44 = 88 cm Keliling 1/2 Lingkaran = 1/2 x x d = 1/2 x 22/7 x 14 = 1/2 x 44 = 22 cm Keliling yang diarsir = Keliling persegi panjang - Keliling lingkaran = 88 - 22 = 66 cm
k=30 + 14 + 30 + 22
k=96 cm
jawabannya d. 96 cm
= 2 x ( 30 + 14 )
= 2 x 44
= 88 cm
Keliling 1/2 Lingkaran = 1/2 x x d
= 1/2 x 22/7 x 14
= 1/2 x 44 = 22 cm
Keliling yang diarsir = Keliling persegi panjang - Keliling lingkaran
= 88 - 22
= 66 cm
