Taman berbentuk lingkaran
Jari - Jarinya 14 cm
Diameter lingkaran
= 2 x jari-jari
= 2 x 14cm
= 28cm
Keliling lingkaran
= 2 x phi x jari-jari
= 2 x 22/7 x 14cm
= 88cm
Luas lingkaran
= phi x jari-jari kuadrat
= 22/7 x 14cm x 14cm
= 616 cm^2
Diameter = 28cm x 1/100 = 0,28 m
Keliling = 88cm x 1/100 = 0,88 m
Luas = 616cm^2 x 1/10.000 = 0,0616 m^2
Pasar bentuk Persegi Panjang
Panjangnya 23cm
Lebarnya 10cm
Panjang = 23cm
Caranya lihat angka terbesar
Lebar = 10cm
Caranya lihat angka Terkecil
Keliling
= 2 x (panjang + lebar)
= 2 x (23cm + 10cm)
= 2 x 33cm
= 66cm
Luas
= panjang x lebar
= 23cm x 10cm
= 230cm^2
Panjang = 23cm x 1/100 = 0,23 m
Lebar = 10cm x 1/100 = 0,1 m
Keliling = 66cm x 1/100 = 0,66 m
Luas = 230 cm^2 x 1/10.000 = 0,023 m^2
