Keliling Persegi Panjang = 2 (Panjang + Lebar) 28 cm = 2 (4/3 Lebar + 3/3 Lebar) 28/2 cm = 7/3 Lebar 14 * 3 = 7 Lebar Lebar = 42/7 = 6 cm
Keliling = 2 (P + L) 28 = 2 (P + 6) Panjang = 8 cm
Diagonal = 10 cm (dari segitiga istimewa phytagoras) Tapi jika mau caranya, ini... (Diagonal)2 = (Panjang)2 + (Lebar)2 Diagonal = Akar [(8*8) + (6*6)] Diagonal = Akar 100 = 10 cm
28 cm = 2 (4/3 Lebar + 3/3 Lebar)
28/2 cm = 7/3 Lebar
14 * 3 = 7 Lebar
Lebar = 42/7 = 6 cm
Keliling = 2 (P + L)
28 = 2 (P + 6)
Panjang = 8 cm
Diagonal = 10 cm (dari segitiga istimewa phytagoras)
Tapi jika mau caranya, ini...
(Diagonal)2 = (Panjang)2 + (Lebar)2
Diagonal = Akar [(8*8) + (6*6)]
Diagonal = Akar 100 = 10 cm
