Bangun Datar Persegi Panjang
Rumus ;
Luas = panjang x lebar
Keliling = 2 (panjang + lebar)
Panjang dan lebar persegi panjang berturut-turut adalah 5 cm dan 4 cm.
L = panjang x lebar
L = 5 cm x 4 cm
L = 20 cm²
K = 2 (panjang + lebar)
K = 2 (5 cm + 4 cm)
K = 2 (9 cm)
K = 18 cm
Penjelasan dengan langkah-langkah:
l = p × l
l = 5 × 4
l = 5 + 5 + 5 + 5
l = 20cm²
==============
k = 2 × ( p + l )
k = 2 × ( 5 + 4 )
k = 2 × 9
k = 9 + 9
k = 18cm
