Jawaban:
78 cm
Penjelasan dengan langkah-langkah:
Keliling persegi
= 4r
= 4 × 14
= 56 cm
Keliling ¼ lingkaran
= ¼2πr
= 1/4 × 2 × 22/7 × 14
= 22 cm
Keliling gabungan
= keliling persegi + keliling ¼ lingkaran
= 56 + 22
= 78 cm
sisi persegi= 28 : 2 = 14 cm
keliling persegi di pinggir 14 × 3 = 42 cm
keliling lingkaran= 2πr=2.22/7.14=88 cm
keliling lingkaran hanya 1/4 = 88×1/4=22cm
keliling = 42cm + 22 cm + 14 cm = 78 cm
