Jari-jari lingkaran = 14 cm
setengah keliling lingkaran
= 1/2 x 2πr
= πr
= 22/7 x 14
= 22 x 2
= 14 cm
Keliling bidang
= 44 + (31-14) + 17 + 31 + 17 + 14
= 44 + 17 + 17 + 31 + 17 + 14
= 140 cm
skala gambar
= 1 : 600
= 1 cm : 600 cm
= 1 cm : 6 m
Keliling lahan sebenarnya
= 140 x 6 m
= 840 m
Banyak pisang yg dapat ditanam
= 840 : 1,2
= 700 pohon
